it may kill it may not but the packvolume is only "tiny and little" relative to something really small, a lot smaller than the whole PC assembly the proper wording is "a tiny bit smaller than xxx". and at that point I'd rather stick with something that has worked for me and others for thousands of jumps and many years. It's not like the BOC is not made from elastic material :) but that's just me ....

The short answer is tha at 600 jumps on the dacron lines you need a reline, no matter how magically sturdy those lines are :) And I personally don't think it'll get worse. And I would also recommend sticking with Dacron - your back will think you later. Not enough time to talk about flaring in a track, but when I free up I will try to add something constructive in the other thread. And of course will also be waiting for some wisdom from mjosparky :)

the theoretical scientist in me could not help it. let's agree that changing the fabric will change nothing else (i.e. the volume of the bridle, mesh, load tapes will not change). the area of a 48" PC is (pi*r^2) = 1810 sq inches the thickness of ZP material is .003 inches (as per http://www.perftex.com/milpara.htm) that gives us the volume of the 48" ZP round @ 5.43 cu inches. a 15% reduction in packing volume will result in a volume decrease of .81 cu inches... points to consider - the ,81 cu inches, compared to the TOTAL volume of the ZP PC cap with all the components will end up being less than 10% of the total volume. the values used are absolute - and are only valid if you can squeeze the very last bit of air out of the fabric. considering my math is not off, the change is quite negligible :) /I am not yuri_base. I am not yuri_base /I am not yuri_base. I am not yuri_base /I am not yuri_base. I am not yuri_base /I am not yuri_base. I am not yuri_base /I am not yuri_base. I am not yuri_base

Probably for the same reason that I explained earlier. But I don't manufacture any gear - probably a good question to ask the people who do. Ask Stane @ Atair. Or Todd@Apex. overall this topic is slipping, and needs to go on the "other" forum

Think about it. a 15% reduction in packing volume of a canopy is a big deal as the material is the bulk of the volume. in a PC you have the mesh, the load tapes and the bridle w/ kill line (remember you do put a good portion of the bridle into the BOC as well). so really, a 15% reduction in packing bulk of the F111 material will be barely noticeable, if at all. on the subject of BASE PCs... Well, quite a few people prefer ZP PCs, and being that the new material is more F111'ish - makes it a moot point. Personally, I would waita few years and lots of test jumps on new material PCs before I venture trusting one in a single canopy environment.

how much difference will a low bulk pilot chute make ?

yes personally I don't understand what you are asking. Low bulk Pilot Chutes IS ? say what ?

Thank you all. it is not TSOd, so not legal to jump as a reserve in the US, unless you are European :)

So, I got a PdF Mayday 7 reserve, DOM 1993 I'll be damned if I can find any info on what it is or even the size. can anybody help ? thanks !

DOMs ? Are the Sabres original Sabres and do they have patches/larger sliders ? what size PDR ? AAD ? harness size and container size ?

While I agree with the intent of the bulletin, the example listed as argument for compliance is flawed. "BACKGROUND: A recent fatality has highlighted the fact that some jumpers are using reverse risers on equipment that was not designed to use them. When improperly mated to these rigs the risers will not release in a pilot chute in tow / face to earth attitude resulting in an extremely hazardous reserve deployment situation and likely entanglement." Can any of you guess as to why this is "flawed"? The statement says that the hazardous reserve deployment situation was caused by improperly mated reverse risers. That implies that reverse risers can be mated properly (i.e. can be used with the rig)

The "new" owner of Reflex has addressed that same poptop problem with the "flapplette mod" http://www.tridenthc.com/flapplet.htm makes sense to me ....

Sure! If you tune a working release system into a non-function than you call it a great idea... Dude. this time you are not making sense. Or perhaps I cannot read. But instead of nitpicking what I said - why not add something constructive to the conversation ? You are not even disagreeing with what had been said - you are just arguing about the wording.

Pardon me? Who gives a damn about integrity risers on a BASE rig? You just do not cut your BASE canopy away in an in-flight emergency.... As you have taken my statement out of context, you are (as usual) absolutely correct. However, the question posted by Sparky was "Can you come up with on thing that is "inherently" right with them?" And have shown the advantages. Why do you think all them years that people had reverse risers on their skydiving gear and thought it was a good idea ? Oce more time - It's a great concept, but does not seem to work well in skydiving environment.

Can you come up with on thing that is "inherently" right with them? Their design goes against a basic principle of rigging and gear design. If it will not improve function or safety it is a bad idea. Sparky your logic is flawed. what's inherently right with regular 3rings ? If A leads to B, does B lead to A ? nope, only NOT B leads to NOT A. It's called a contrapositive. Anyways. the reverse, or also known as Integrity risers have some positive qualities over "regular" a) they do not have a grommet in the middle, thus theoretically being structurally stronger. Yes, we all know that the difference does not matter, because at a small percentage of the failure point your body will fail first. b) they allow an easer material inspection while geared up, while at the same time protect the 3 ring c) when packing, there's no wear on the 3 rings and the white loop (which so many people don't pay close attention to, like they should since the failure of the white loop low to the ground will really fuck you up:). In my book that's both an improvement of function(strength) AND safety(less wear/more snag proof) with all those things taken to a theoretical scientist I would say the reasons for Integrity risers are spot on. Furthermore, if you notice that no-good Brit, tea-sipping chap Andy Copland posted a picture of his BASE rig with integrity risers - you may not realize this, but they are quite popular with BASE rigs, mostly for reason C, as packing is a lot of times done in on less than ideal surfaces, and when stowing the lines in the tailpocket of the freepacked canopy one drags the container to the packjob, not the dbag to the container. Yet another point, quite well reinforced by Kelly, is that if one does not have to worry about cutaways as much as skydivers - the Integrity risers a just fine. Do I think they are ok for skydiving - yes, I can think of a few times where they may work fine. Will I advocate them or put them on peoples skydiving rigs without their knowledge ? Hell no. But I will not hesitate for one second to use them on BASE gear, as I have on 1 of my rigs. whatddya say ?

As a data point can you let us know if the 300 jumps you put on your Sabre were all since new or did you buy it used with xxx amount of jumps on the lines ? Because you are confusing a lot of people with that bit of information - microlines should not need replacing due to fraying at 300 jumps unless your slider grommets feel like sand paper :) Personally I have had plenty of original Sabres and Sabre2's relined with good results. For the most part openings have been "Back to stock". If you have an original Sabre get PD to put a newer large slider on it if you have not yet. as far as opeinig when you are flaring out of your track - how does that soften your openings ? When you are just flaring out your speed has not been reduced yet so your canopy is thrown into a higher speed airstream. If anything that should swing you more as you are not only going down but also forward. I again ASSume that you mean you did not bleed off all of the speed you built in the track. cya

Yes the drop zones I go to will have no problems letting COMPETENT people jump it. But getting your PLFs down in the extremely unlikely case that you need to use the round reserve should be a good thing to practice.

if it has BOC conversion and Cypres conversion done, and the velcro is strong - $200-$400 is what it will sell for. And get the rigger to sew the split d-bag shut

got a story ? perhaps a reference ?

Amen to that. get a second, UNBIASED opinion.

Rigger Pete @ Lodi is da bomb. Can't go wrong with him.

I guess a newbie has to also realize the levels of getting screwed you can get scammed out of your $$$ you can be sold gear that is not good for you (doesn't fit, canopies too small/big) you can be sold gear that's not good for anyone (outdated, has service bulletins, just old/ragged out/unsafe) Don't think that the gear is "good" just because it fits you - an old Vector1 w/ 5 cell Swift Reserve and a ragged out Maverick main can be advertised as good beginner gear, but it's very far from what most people would call "good beginner gear". use common sense and good luck

Out of curiosity - can anyone remember the year that Racer stopped doing velcro riser covers ?

and on this note please also don't take all the advice you take from the internet as valid. I have sold a few rigs to guys in Thailand who used WU. I have also been paid by WU from Belarus, Russia, and UK. If I would have been as close minded as Remster suggests, I would not have made those sales. WU is a great tool - just make sure to use it properly. Let me explain : To verify that you in fact did get paid GO TO THE WESTERN UNION OFFICE and CASH those checks. Once you got COLD HARD CASH - then you can ship the product. What SCAMMERS would want you to do is ship the gear immediately following receipt WU checks in the mail (which are either fake, or like I had in one case real checks that had a stop payment on them). Like the posters above said - USE COMMON SENSE. But don't be narrow minded.

the classifieds are fairly safe as long as you have common sense. I highly recommend getting the seller ON THE PHONE and talk to them. No scammer will ever give you their phone number, nor will the y be able to talk the skydiving lingo.
