Downsizing...how much is too much? Can't Post

Im new.
No way around it and I'm not trying to push the envelope a whole lot. The flying part of my current skill level isn't what concerns me a whole lot. While I only have about 40 jumps, I have 2 hours of one on one tunnel time that has helped my body control in flight tremendously. I understand I'm an extreme novice, but with my freefall ability (belly flying) I have a lot of confidence. But that is gravity taking care of itself. The real skill to skydiving in my opinion is canopy control.

Currently I've been jumping (renting) a Silhouette 230. I feel good on this thing, I've spent a lot of time pulling at 5000+ to get the hang of it ie. riser turns, stall point, dives etc...but now I'm looking to fill a container that I purchaced with a Sabre2 210. I wanted to buy a container/ main that would give me hundereds if not a thousand jumps without me getting bored. My landings have been solid. have not crashed in, plf'd or even been close on the Sil 230. I guess my question is; How do I know when i can cut 20 more square ft out and how much different is the semi elliptical compared to the square ram chute Ive been using? Am I ready because I feel ready? As a long time motorcycle racer I've seen my share of crashes due to people thinking they are ready.

my stats are as follows: 6'00''
exit weight of 215

Re: [baRRRpirate] Downsizing...how much is too much? [In reply to] Can't Post

Here is what I did... It may not be the right path for everyone and it may not even be the BEST path for me.

I had a second hand fairly cheap rig for a year. The main was a Tri190. I was loaded about 1.2:1 at 60 jumps (which according to many is pusing it a little bit.) I had the cash and wanted to make a long term gear investment. So i bought a container that i could really go up or down a lot in.

My I got a Storm 190 (7 cell=smaller pack volume) and put it into a container made for a 9 cell 170.

So if in the future Want to down size I can go from this to a smaller 7 cell, or I can switch to a ZPX 190 9 cell, and then down.

Regardless of how I do it this container will last me at least through my next two sets of canopies. That being said, I probably wont be downsizing any time soon given my lack of currency due to school:-/

** second disclaimer not best path for everyone **

Based just off of wingloading/canopy choice a Sabre2 210 is an acceptable canopy at your experience level and weight. Make sure to get a larger size reserve as well!

Thank you very much for the article...I've seen the sizing chart before, however, I tend to take generalities into consideration but don't necissarily abide by them. I feel if certain skills are met or not met, that sizing chart can be shifted either way. The article however seems to have a lot of really good info. I will definitly read the entire thing. I have also been reading Canopy and Its Pilot by Brian Gervais

I'm always amazed when people say stuff like this. They pay lip service ("oh yeah Brian Germain's book is simply amazing, he's my canopy flight guru and taught me so much, you should buy his book too") but when he publishes a line in the sand chart that literally says "this should never be exceeded by anyone" suddenly he's just talking generalities.

You know, for other people.

What do you have, different physics?

Just go right ahead picking just the advice you like, from the teachers with tens of thousands of skydives who dedicate their lives to teaching this stuff. The other parts aren't so important anyway.

you dont get it. you want to stand on your high horse and think you know me. i have the book. i have the chart. i take all advise into consideration. there are a lot of "lines in the sand" that are created to teach the lowest common denominator, those are guides and recommendations. when i say i steer clear of the generalities its because i dont base my decision solely off of a piece of paper telling me where i should be. there are other factors to take into consideration. with the aid of the chart, the book, practice, coaching advise and critiques, i, as well as my mentors, will decide what is best for me and my advancement in this sport. its not "lip service"...its gathering info.

your comment made you look like big mouthed cocky smartass that i have come to recognize are prevelant on this site.

why post a comment if you dont have something respectful and relevant to say?

im posting on here to get advise from friendly educated people, not to be an asshole. you should take some notes!

Re: [baRRRpirate] Downsizing...how much is too much? [In reply to] Can't Post

When I had 40 jumps, I went from renting a Silhouette 210 to a Sabre2 190. I weighed about 185 lb at the time. I personally feel I should have stayed on the 210 for another 50+ jumps. I could easily land the Sil/210, but had a lot more trouble with the S2/190.

My opinion is stick with the 230 till you have at least 100 jumps. The Sabre2 IS sportier than the Silhouette. Add to it the heavier wingloading, and it's just a risky decision. You *probably* won't get hurt, but I'd attribute that more to luck than skill, as was my case.

Get where you can land the Sil from half brakes with no issues, where you can turn 45+ degree DURING your landing flare, where you can land it on rears, and consistently (19/20 times) put it within 50 ft of where you want. Pull lower, get comfortable pulling between 3,000 and 3,500 ft and doing the same thing.

No, you don't get it.

You want advice for the above-average, when no one besides yourself (i.e. someone who is an experienced canopy pilot) has determined that you're above average.

You may be above average. However, at 40 jumps, you don't have enough jumps to have established that, and it's not something you establish by yourself anyway. Above average includes not only standing it up, it also includes judgment, knowing when to fall down, an incremental approach to swooping (rather than trying to go big and impressive right from the start), and an awareness of all the other canopies in the air, as well as a whole lot of other variables that need to be in the background before you start to get serious about swooping. Things like wind steadiness, where the burbles tend to be at your DZ, where the ground is least and most bumpy, and a whole lot of other stuff.

You're looking for the folks like you. You might want to head over to the swooping forum down below, but, unfortunately, you'll probably hear much of the same there.

If you really want to swoop, you're better off learning on the slightly larger swooping canopy (I'm told a Sabre 2 is really good for that, because it scales well, and behaves like a swoop canopy), which will let you do much edgier moves with slightly more forgiveness of errors. And yes, you are exceedingly likely to make mistakes. Because it's not an exact science, there are random factors that enter into the landing equation, and you have to deal with them, too.

There are people who haven't hurt themselves seriously even though they started off on too small a canopy. But some of them will tell you taht they really started learning when they began that incremental approach, and sometimes even upsized.

Re: [voilsb] Downsizing...how much is too much? [In reply to] Can't Post

Good advice. I would add this...

Coming from a motorcycle racing background as well, don't downsize until you can wring every last bit of performance and capability out of that canopy. I am about your size as well, my 210 Spectre is my first canopy, flew 230's on student status. The Spectre (and Sabre etc...) is a completely different canopy in terms of performance and flight characteristics.

Downsizing once you can just LAND safely is like riding a Ninja 250 until you can take a curve without your feet down and then hopping on a 600. Big difference between that and learning to drag knee/pegs/exhaust and killing someone's ego on that same bike. Learning on a bigger, more subtle canopy/bike will make you a better pilot on the bigger stuff. (ask me how many people I've embarassed on my old 250...)

oh i get it wendy. and if people would read my entire post and process it before asking me rhetorical questions like "are my physics different" i wouldn't have to write crap like that. all i want is advise not smartass judgement. in my response i even mention coach critiques and mentors.

my original question was asking about the difference between sabre2 and a silhouette. also what are good indicators for being ready. people on this site seem to want to say how badass they are and how much of a rookie you are vice imparting wisdom and knowledge.

thankfully certain individuals did answer my questions with articles and advise.

not interested in swooping right now, just interested in fitting a 210 in my container and learning tricks and drills to tell when im ready to use it....i mean come on, im not trying to weigh out a huge wingload.

it gets frustrating when you read posts for advise and you see so much condecending comments.

Yup. And it gets really frustrating when someone asks for advice and then dismisses the good advice that is given because they don't agree with it or like the tone.

You were given the suggestion to read through both Billvon's downsizing checklist and BG's chart/article. The two are pretty much the standard for downsizing.
And you implied that they were "generalizations" aimed at the "lowest common denominator."

Which is the standard response from those who intend to disregard them.

So be careful before you blame everyone on here for wanting "to say how badass they are and how much of a rookie you are."

You are starting to sound like the typical "Madd Skilz" newbie who's "special" "above average" and doesn't need to follow the rules.

That doesn't mean that you are like that, but it sounds like you could be.

And, FWIW, a 210 Sabre2 would be a reasonable next step, and it seems that you are ready for it. But I don't know you and I've never seen you fly. So why would you follow my advice?

This place is great for info on gear, technique, and other "generalizations."

And boobies too. Cool

Specific advice for specific jumpers in specific situations?

Not so much.

Related to this, a Sabre2 210 won't pack a whole lot smaller than a Silhouette 230. The hybrid fabrics help.

When you buy used at a fair price, mains and containers each depreciate about $1 per jump. Assuming you don't buy custom gear in your colors too soon you can spend the same money whether you go through 1 container or 3 and 1 main or 6 in 1000 jumps although it'll probably cost less to go through more mains because that lets you avoid getting to where you need new lines ($200-$300, which can happen in just 500 jumps with Spectra lines that go out of trim) and with good negotiating skills you may even turn a small profit through buying low and selling high.

Health insurance deductibles can be $500 on a good employer provided plan and $5000 on a catastrophic plan, co-insurance can run a few thousand more, and disability insurance usually only replaces 60% of your pre-injury income. This can really add-up, especially when one injury can imply three surgeries over a period of years to get you back to your original state. This disregards how much things like stretching nerves hurts.

Think about that a little bit and you'll realize that trying to buy one parachute and container that you'll grow into isn't buying you anything but could cost you a lot.

In reply to:
exit weight of 215

As people have noted the skills outlined by Bill von Novak and Brian Germain are good pre-requisites for down-sizing. Brian's 1.0 + .1/100 jumps with adjustments dictating larger canopies is a reasonable minimum with bigger being better.

Re: [DrewEckhardt] Downsizing...how much is too much? [In reply to] Can't Post

Thank you everyone for the posts. I'm sure I will be hitting up these forums again to ellicit info on certain things so I would like to clear a couple things up to maintain good standing.

I felt it was I was clear when I said I was new. I want to get better at piloting and I take all info, recommendations and coaching seriously. Apparently the idea of me saying that Brian Germain's downsizing chart was a generality struck a nerve with certain people. I understand that there are experienced jumpers that have either been on the recieving end of or had a friend pay for a bad dive so they look out for the new guys best interest with words of wisdom. I think that on this website and in the sport as a whole there is loss of tact in a lot of areas. By saying it was a generality, in my mind, im correct. The way I see it is if the chart says I need a hundred jumps to get where I need to be, thats general...what if I need two hundred. It could also work the other way (not quite that literal, but you get the point). I was pretty clear with saying I take all info into consideration. To me, there is no substitute on paper that will equate skill and on site coaching by instructors.

What my intentions were with this post, was not to seem like I have "mad skillz" but to convey that I take this serious. I want to start on a rig that is slightly under what I'm jumping now and wanted insight. I am constantly talking with other jumpers who I jump with that are experienced but wanted to branch out for other opinions. I AM IN NO RUSH TO DO THIS.

Thanks for the posts with valid info, I'll re-read through all of them periodically. Knowledge and practice will always yield high results.

It is wrong to think ahead of time that you'll be bored under a 210. It may be, but don't predict it ahead of time, and you certainly don't need to worry about the resale value of such a rig.

Another factor that you may or may not be considering is that the 'window' of what's acceptable will shift a little based on jumpers both bigger and smaller than average.

In your case, you're bigger than what I consider 'average' for a male jumper, and as such you might be able to err 'slightly' on the side of a higher WL. The reason being that for you to be at 1 to 1 puts you on a 210 or 220, which is still a fairly large canopy.

Consdier the other end, a small female with an exit weight of 145 lbs, she would end up on a 150 sq ft canopy to be at 1 to 1, and that's a fairly small wing for a new jumper, even at a lower WL.

With all that in mind, the Sabre2 210 doesn't seem like a bad choice. Provided that you (and your instructors) are comfortable with your skills and the idea of you jumping a 210. Choose a day with steady, light to moderate winds, and pull high to give yourself some time under canopy to check the stall point and do some practice flares (ask an instructor for the exact procedure fo both). Pulling high will also let you easily land last, with no traffic around.

I don't get a bad vibe from you 'yet', and said the same in your other thread. Lot's of guys take a turn for the worse once they get a handful more jumps and have some success with new skills. We call them 100-jump wonders, and the basic idea is that they start to overestimate their knowledge and abilities. Don't turn into that guy.

point taken.

I believe in this:
Plan, execute, analize (how can I make this better)

I feel I'm getting close to the Sabre2 210 I was asking about. I am not ready as of yet in my opinion, but I'm close enough to start to think about it. I like the comment you left in my other thread..."the simple fact is you only get 1 landing per jump."

That is a very simple and smart way to look at it. Until I can control a canopy in any condition. Have it do what I want it to do, and if my 1 landing per jump happens to be downwind off site...can I control it. If the answer is no then stay with what you got.

thanks again for the advice

The important parts of it were

2. Those really aren't just guidelines.

Keep reading, and remember the Rule:

Well, you've shown good judgment in taking 2 hours of tunnel time to learn how to fly better than most at 40 jumps.

May I suggest employing the same judgement by taking a Canopy Skills course on your existing canopy.

Hi, your profile doesn't say where you are located but if you are in the US I can highly recommend the http://flight-1.com/sport/ courses. I did 101 and 102 this year. I can say that after doing these classes that 'you don't know what you don't know'.

This is coming from someone with 1000's of hours of fixed wing flying who could fly a pattern and land my canopy pretty well where I planned on the DZ from the get go.

I don't want to come off as an ass, but your not special. I down sized from 220 to a 190 at 40 jumps under the guidance of my mentors. This was not an aggressive down size, it put me at 1:1. What happened? I broke my ankle.

Anyhow, keep asking questions my friend and have fun.

In all fairness to the OP, he did also start a thread in the canopy control forum where he was looking for info on canopy control courses. I'm 99% sure the other thread came first.

I don't know the guy at all, but from both threads, I don't get the vibe that he's on the wrong path. I do mention this, but back it up by letting him now how quickly some guys veer off the right path, and not to be that guy.

When you break a bone, you have found your point. Recover, and start over a size or two up.

If you remove yourself from the gene pool, well, you definitely downsized too much.

A Pulse packs a size smaller and is a blast to fly. You can maximize a container's time in your progression with starting on a larger pulse in a container that is made for a smaller wing.

IMO it gives more performance than some other canopies the same size. It really is fast and fun. Easy to pack too.

Have you thought about demoing? PD has an excellent demo program. I would try several different wings in the size your instructors suggest just to find out what you like.

Re: [EFS4LIFE] Downsizing...how much is too much? [In reply to] Can't Post

I have a similar question, I currently weigh around 220 which puts my exit weight around 242, I'm fairly new to the sport (about 30 jumps) and have a goal of getting down to a 210 so I can actually rent some freefly friendly gear in a little while (buying a rig is out of the question for a little while). I currently fly a 240 with no problem but am apprehensive about taking the step down to 220 (1.1) much less 210 (1.15) despite everybody at the dropzone stating there's no difference between 240 and 220 (at which point I laugh).

What would be the proper downsize guidelines for that? I've read the Big Air Sportz guideline which suggests 140 - 220 jumps before getting to that point at my weight which is a bit of a bummer but understandable. Unfortunately the DZ I go to also seems to be pretty much slim pickings with rental gear, and I often have to upsize to a 260 or 280 (there are no 230s).

I have no real interest in downsizing to swoop or to do any kind of advanced maneuvers. I just want to get the hell off student gear.

Unrelated but I was always curious - Does the increased wing load effect canopies over 200 to the same extent as those under? ie - if I jump a 1.2 wingload on a 210, I'm assuming it won't be the same as somebody jumping a 1.2 wingload on a 135. Probably wrong on that though.

My advice would be to not go higher than 1:1 wing loading under 100 jumps.

-Buy your own gear?

-Spend the next 67 jumps working on your belly skills?

What makes your student gear unsafe for freeflying. I see our students in all kinds of attitudes, sometimes intentionally. If properly pinchecked and in good condition, most modern rigs will do for a little freeflying, won't they?

I'm guessing you meant BOC pockets being stretched out and pilot chutes slipping out? If so, yes, that's one of my thoughts. To me that means the DZ rigger needs to do a little maintenance on the rigs they're renting out to people.

Bridle protection is very important too, but more a function of rig design and proper packing, IMO. Smile

Yes sir baby!

Bill Von Novak's article is reality. You need those skills regardless of downsizing intent. And you need them on each and every canopy make/model/size you fly.

Brian's is not reality. It is nothing more than a conservative recommendation. The chart takes no consideration of a host of variables. Going simply by jump numbers is insane.

"I have 500 jumps but I have never done (insert skill here)."

Again..get your input from your local guys.

In reply to:
Unrelated but I was always curious - Does the increased wing load effect canopies over 200 to the same extent as those under? ie - if I jump a 1.2 wingload on a 210, I'm assuming it won't be the same as somebody jumping a 1.2 wingload on a 135. Probably wrong on that though.

From the SIM--Category C:

f. With the same wing loading a smaller canopy of the same model will exhibit more lively performance characteristics.

(1) faster turns and turn response

(2) quicker dynamic stall response

Knew I saw it somewhere! Thanks.

In reply to:
My advice would be to not go higher than 1:1 wing loading under 100 jumps.

-Buy your own gear?

-Spend the next 67 jumps working on your belly skills?

What makes your student gear unsafe for freeflying. I see our students in all kinds of attitudes, sometimes intentionally. If properly pinchecked and in good condition, most modern rigs will do for a little freeflying, won't they?

Loose BOCs and a general lack of trust in using a different rig every time I show up is all.

I currently weigh around 220 which puts my exit weight around 242

First off, get on a scale. 22 lbs is shooting low for gear + clothing for a guy your size. A rig that will hold canopies your size is going to weigh more than 22 lbs on it's own.

Quote:
I currently fly a 240 with no problem but am apprehensive about taking the step down to 220 (1.1) much less 210 (1.15) despite everybody at the dropzone stating there's no difference between 240 and 220 (at which point I laugh).

if I jump a 1.2 wingload on a 210, I'm assuming it won't be the same as somebody jumping a 1.2 wingload on a 135.

You're not far off here. When it comes to the 'difference' between one canopy and the next, wingloading is a big part of how much difference there will be. A guy who's 175lbs, going from a 240 down to a 220 will not notice as much difference as you will. The higher up in WL you go, the more noticable the differences will be between sizes.

As an example, think about the difference you feel between jumping a 280 or a 260. It's not going to be as noticable as when you move from the 260 to the 240.

Moving on WL as it relates to canopy size, you are correct that a smaller canopy at the same WL will perform differently than a larger one. This is the reason that the '1 to 1' rule of thumb for beginner WL does not apply to smaller jumpers. A 95lb girl with an exit weight of 120lbs should not be jumping a 120 sq ft canopy in her first rig. The smaller size of the canopy, even at a 1 to 1 WL, will not be as forgiving or easy to handle as a 170 or 190 at the same WL.

However, that knife cuts both ways. Larger jumpers can often err on the side of a higher WL due to the same factors. The larger size of a canopy will reduce the performance to a degree, that you can get a reasonable level of forgiveness at WLs north of 1 to 1.

With all that said, none of those details matters when it comes to downsizing. All that counts are your skills, the opinion of your instructors, and your confidence level. If any one of those three do not point toward downsizing, then don't do it. If you can demonstrate the skills on Bill Von's downsizing chart (and by demonstrate I mean that you do each of them at least 5 times successfully), and you have the backing of your instructors or a local canopy coach, and you feel like it's a good idea, then try jumping a canopy one size smaller.

Before your first jump on a new wing, get a briefing on how to evaluate a canopy in terms of glide and the flare/stall point so you enter the landing pattern with a good idea of what to expect. Pick a day with calm, steady winds, and plan to pull higher than normal to give yourself extra time under canopy and a better chance to land last (with no traffic).

Another idea is to see about a demo 230. PD has a great demo program, and they offer a good number of 230 sized canopies. Talk to the people at your DZ and see if you can rent a rig for the day, and have one of the riggers hook up the demo into the rental rig (it's not that hard, they come on risers).

Brian's chart is page 1. There's plenty more to read after that including the following comments...

"Due to individual differences in natural ability, judgment and demonstrated in-air awareness, there must be allowances for variability with the recommended size. To fit every canopy pilot into a finite formula is not reflective of the true nature of the situation."

There are also exercises listed in the document.

Saw a guy hook in a Pulse 150 on Tuesday and basically show his ass to all of the xfire / katana er al fliers (the pro guys training for Dubai gave him a look, too).

As we walked through the crowd to packing he mumbled "talk to me when you're ready to dowsize.". Granted his daily wing is a sub 100 velo...but it was way impressive.

Exactly why you cannot discount Brian's recommendations as 'insane'.

This past summer I attended 2 canopy courses with 2 different coaches from PD. At the end of the courses, they both recommended everyone continue with ongoing training and skill development and working with other reputable coaches -- including coaches not affiliated with PD. One of the guys from PD mentioned Brian by name.

BV's checklist is an essential set of skills that every jumper should be able to perform. Brian's chart, recommendations and exercises complement that checklist. They are both valuable resources.

Didn't say you should. Please don't read more than what is there.

Re-read my comment. It has nothing to do with Brian Germaine. It applies across the board.

Yep. I would not tell anyone to avoid Brian. I recommend him for certain things myself.

Yes indeed they are. All that is well known.

Maybe this is what threw you off...
Brian's chart in and of itself, is not reality. Even though it says ..."must not..." There is much more to it and BV points that out rather well. Brian is trying to draw a line in the sand and you know as well as I do that is not what happens in the real world. We've discussed that line in the sand more often than once already. Would USPA adopt something like that? I sincerely doubt it. Jumpers throughout the country would be screaming.

Brian's chart PLUS the text is valuable information for for all of us. Just the chart is the recommendation...that's all it can be at this point.

But to his credit, I understand he no longer promotes that and has been just recently convinced of the physics of exit separation.

I would suggest that you put your axe down and step away from the grinder, but you will probably continue to dig up the prior discussions with Brian about the 45 degree rule ... even in new threads that have nothing to do with exit separation. Oh well, carry on...
