  1. It’s not just shorter lines, it’s air resistance and drag as well. A smaller canopy has a lower profile and less drag/air resistance. It accelerates faster and takes longer to slow down. What we have to understand is this whole WL conversation is not linear. In fact, it’s chaotic. Most people giving advice regarding WL or canopy size or canopy type almost never ask: WHY. Why do you need a smaller canopy or a different model? What are you trying to accomplish? What are your short-term and long-term goals? For example, If someone comes to me and says, “I started skydiving because I want to fly wingsuits” or “I started skydiving because I want to BASE jump,” my WL and canopy recommendation would be much different for them than someone who said, “I got into skydiving because I want to have fun.” What’s funny, is a lot of people don’t know they want to “downsize” until they see their instructor or the other “bad asses” of the DZ swoop in. They see the top of the totem pole wearing little rigs and flying tiny canopies and emulate them. Before giving anyone any advice, ask yourself, “what are they trying to accomplish and how can I help them accomplish that goal?” Don’t force your aspirations and goals on them.
  2. I would like to know the kinetic energy calculations of no flare impact of various canopy sizes at various WL as well as estimates of kinetic energy calculations of impact of various canopy sizes at various WL of mistimed flares after low turns. If there are any math nerds here who would know how to do such calculations, I’d be interested in working on it with you.
  3. Got it, thanks! Is that the only sanction that happened as a result of a BASE rig out of an airplane?
  4. Are there any documented cases of penalties for violations of 105 for pilot or skydiver jumping BASE rig from plane?
  5. I’m pretty sure Strong has a history of military and aerospace design/manufacturing that they want to leverage for contracting purposes.
  6. I flew a pull-out racer in the 90s for my first 500 jumps and loved it. I’ll admit, it gave me a little bad habit of a weak throw that sometimes still haunts me today. For CRW, I’d recommend it if you want a more direct inflation/pin pull. However, it may not be necessary. On a slight side-note, PC hesitation is a bigger topic in BASE compared to skydiving and how you are packing/stowing can cause hesitations. Tom Aiello talks about some things to consider Here, Here and Here. He also discusses a standard BASE PC packing method Here. Maybe try packing your PC like a BASE PC to see if that solves your hesitation issue before changing the deployment method.
  7. Is this not mounted inside the shell of the helmet?
  8. You can buy non-adhesive tinted window film as well in case you want to experiment without commitment. A tinted visor may also help.
  9. You pitch at 3,500 ft. Three seconds later it clicks in your brain something is wrong. You are at 3,000 ft. You will reach your hard deck in three seconds and your AAD will fire in twelve seconds. How many seconds do you spend trying to clear it? How long will it take to successfully pull your cutaway and reserve handles?
  10. The skydiving world could use more people doing what you are doing. Great work!
  11. For context, SLJM; AFFI; TI; thousands of jumps: cut away and then go to reserve. (I like to think) I would have also kept reserve brakes stowed until finished sorting out the entanglement. Also, how do you fold your PC & bridle? This data point is of great interest to me.
  12. What you’re expressing is sort of like asking how to get more people interested in Style & Accuracy or 10-Way Speed Star or CRW. The culture and interest of drop zones change as new disciplines are introduced. The reason for this is people are always looking for new and fresh things to do as well as people look up to the top of the skill food chain and take cues from them. Whatever they are doing is often what people strive to do. People get interested in skydiving for myriad reasons. Often it is for friendship and connection with like minded people. If the people they are drawn to are focused on a specific discipline, they will want to do that discipline to be a part of that group. What discipline a drop zone focuses on is an issue of drop zone culture. At most drop zones, the cool kids aren’t doing 4-Way. There are some that do have a large contingent of people focused on 4-Way, but, for the most part, the cool kids are “free-flying.” So, how do you get more experienced jumpers interested in 4-Way? Well, that depends on how much energy you want to spend pushing a large rock up a hill. What you could ask is, “what am I trying to accomplish by participating in this hobby?” If you enjoy 4-Way and want to improve in RW, convincing experienced skydivers to get on your 4-way train is probably the most difficult way to accomplish your goal. The good news is there is a way for you to accomplish your goal and that’s to work with new skydivers as they progress to whatever is their ultimate goal. Belly Skydiving skills are a pre-requisite for all other disciplines. I suggest you embrace working with new skydivers and coach them through this Basic Belly Flying Progression. If they spend 30-minutes in the tunnel and go through the Kinesthesia Dive Program in the air with you, they will be very competent skydivers by the time they hit 100 jumps. This will give you the ability to improve your skills, make new friends and give you a new found purpose at the DZ. The other option, if it’s available, is to choose a DZ where the culture embraces 4-Way and FS. Lastly, instead of having a home DZ, you can find other like minded belly flyers and travel and do mini-camps with them. I hope this helps. Good luck!
  13. “Ideally” and “shouldn’t be a problem” are points on a risk spectrum.
  14. Ideally, for turn rigs, you are best off with identical set ups. If you have multiple rigs for multiple uses like, RW, wingsuit and or CRW, you might not have the option of identical canopies, so, you must be aware of your landing pattern, last turn altitude, sight picture, etc.
