  1. That would be my guess. Dacron is far more bulky and less slippery than spectra, so I can image it is more prone to tension knots. But is is just speculation on my end.

    I had a Lotus Max 136. I was quite happy with the way it flew. For some time I had shitty openings, but I tracked that down to a fully magnetic bag that was a tad too small or whose magnets were not strong enough for that canopy. Once I replaced the bag with a normal bag the openings were fine. It is comparable to a Sabre 2. But honestly I am not sure the airlocks make a big difference. A bit for sure, but if the airlocks are deciding factor between jumping or staying on the ground, then you should stay on the ground regardless of the airlocks.
  3. That is a 360 camera, and the video is also 360. You can turn the POV in every direction by dragging with your mouse. I suspect you just played it and looked at the video. I am not sure if you can turn it on a phone, but I would assume you can. Regarding the twists, it looks to me like you pulled on your left risers and that induced the twists. I flew X-Fires 124, 113 and 102, and in 400 jumps with them I had twists twice (once with a 113, once with a 102). At least one of these twists was self induced (pulled half in a track and with a shoulder definitely lower than the other one). X-Fires open remarkably well. Honestly I doubt that at 340 jumps you are ready for that canopy. An X-Fire 124, at 1.57 is nothing to mess with. Most people recommend that at about 2x your experience. I think that that inexperience played a role in your twists. Be careful, I knew people with more experience, a less aggressive wing and less wingload, that crashed and died in otherwise perfect conditions.
  4. I think it is a "philosophical" question. Some people consider them a gimmick and unnecessary or even bad. I guess the people at UPT are some of those. The only clear advantage I see for the chest articulation, is how much easier it becomes to do MLW shortening/lengthening/replacement. On the flip side, you have more "flexibility" in an area that probably should not be that flexible (the harness could move around more, and it would be easier for it to slide down your shoulders when you are in head down-ish) I think they can be a great thing to have if you buy second hand and you are not sure of the fit of the harness on your body, but I would avoid them when buying a new harness.
  5. That's very good info, I didn't know that! The volume chart website does not mention it at all:
  6. Of course, we can agree on that. But comfort is subjective and varies from person to person. The points I made regarding taller folks are irrelevant if you are flexible enough to reach further up (I had a shoulder injury that kept on the ground for a few months because I couldn't reach my PC, so I have that more present than most) or if your disciplines do not involve using a lot the hip articulation. At the end of the day, YMMV.
  7. You said that your curv is the most comfortable rig you've ever had. I never contradicted that statement. I am not sure what your point is. If you think my reasoning is wrong, and have the time, please correct it.
  8. Just to clarify my previous statement: I am not saying Curvs aren't good for taller folks, just that IMO, at least on paper, they are not catered to these jumpers. To elaborate a bit more: - The lack of long version of the containers means that -unless it is compensated somehow*- the PC will sit higher on the back. If you are flexible enough that is not an issue, but that's something that everyone needs to evaluate for themselves. Wingsuiters, specially the ones with big suits and long bodies, tend to want long versions, to reach the PC easier and to minimize the chances of the wingsuit fabric getting on the way. - The hip ring junction is far higher than on vectors or javelins. Depending on the length of your body, it means that this will be more or less aligned with your hip articulation. The design of the curv (or unisys harness in mirage, or Infinity) probably helps in keeping the leg straps more "in check" and prevents them from moving too far down the legs, and it is probably pretty comfortable, but there is a limit as to how aligned it can be with your hip articulation, since the lateral will be much higher on taller folks than on shorter ones, and that limit can impact flexibility a little bit. You can check, with your rig on, if when you move your leg up or sit in your harness, the leg straps slide on the ring or of the whole webbing moves and there is no slide on the ring. This might not be enough to be uncomfortable, but it is there. I think this is one of the reasons why Mirage offers both style of hip junctions on their G4s. * This "compensation", if it exists, would need to lower the container without putting the 3 rings too far high, so it needs to be longer on the shoulder area, which will mean longer riser covers, which I guess could look awkward or be more prone to problems. The container would also look awkward hanging so much down the back. This is just speculation on my end, I have never seen a curv done for a tall guy, side by side with a curv for a regular guy, so I can't really make a statement out of this.
  9. - Get a Vector because they have higher resale value - Get a Vector because they have a MARD with Collins lanyard - Get a Vector if you are fairly tall guy (hip rings on the laterals make the hip junction on the Curv too high IMO if you are on the tall end, and Curv does not have long versions of their containers) - Get a Curv because they are IMO the top container innovators in the last 10-15 years (nobody else introduced anything new in a long long time -MARDs aside-) - Get a Curv because of the slimmer profile (due to the superior closing tabs) and naturally tighter fit (due to the bio curv) - Get a Curv if you like it more and the lack of collins lanyard does not bother you
  10. I think you should give a shit about what people think. And why they think it. If someone with more experience tells you that you are not fit for a given jump, maybe they have a reason for it. If their reason is that they are assholes with an ego too inflated, well, then you would be right in not giving a shit. But if their reason is that you are way above your head, and that the plan they are planning to do is too much for you to handle at your experience, then you should be humble, patient and learn step by step. If your profile is right, you should understand that your experience is quite low, and there a lot of jumps that are not for you right now. Even world class athletes were babies once. Your time will come if you are serious about the sport, and you keep jumping, improving and being safe. Those are the only things that matter at this moment in your skydiving career.
  11. I do ask that sometimes if I am jumping with people I don't know. I don't want to go on a super steep angle, a complex jump or a jump with too many people, if this people can't handle it safely. If I don't know them, the quickest way to estimate it is asking that question. Jump numbers are just a partial answer of course, but a good and quick indicator. For me it is a safety question, as well as a planning question. I ask also if I see someone with a questionable canopy choice (read it as in "too small") for someone with low experience. Again, that is for me a safety question (in this case not mine, but I don't want to see anybody hurt, had my share of it already)
  12. Thanks for your input Jim and Jerry. You are way more knowledgeable than me, so I don't want to contradict you and I agree that the time to fill a larger canopy is necessarily longer than the time to fill a smaller canopy for a given airspeed. Also larger canopies tend to be "higher" (have more distance between both skins), so the volume increases significantly more than the surface. From that point of view, I totally understand that smaller canopies might have higher loads on deployment than larger ones, under normal circumstances. But I meant a catastrophic opening scenario, where inner inflation might play a secondary role. Simply the drag of the bottom skin when spread. Imagine a slider-off deployment with a single skin canopy. The drag from a fully spread bottom skin on a large canopy is much larger than the drag from small one, so the deceleration is also larger. That was the scenario I was talking about. Fully spreading a large canopy takes longer than a smaller one, but I expect that the additional time needed to spread a larger canopy does not offset the much larger drag a large canopy can create. That was my way of thinking to explain the trend that most folks incapacitated on catastrophic openings, had those openings on large canopies. Maybe there is something else to consider, and my reasoning is totally off.
  13. I don't have any specifics. But that has been the fix for some canopies well known for opening hard (ie: Sabre 1). But there are two things to consider: - It is a delicate balance. If the slider is too big the opening might take too long, or never happen (the slider might hangup all the way up) - The reason catastrophic openings happen is because the slider comes down prematurely (which could be due to a variety of reasons). A larger slider does not guarantee a proper deployment either. I can imagine it could help, but I wonder if the help is marginal
  14. From what I recall, normally the brutal openings happened with large canopies. I haven't seen or read about a brutal opening in a small one. Makes sense also, for 2 reasons I think. 1. Many large canopies have the same slider size than medium sized canopies. The storm for instance has the same slider all the way from 97 sqft to 230 sqft. Others make 2 sizes or styles (normal slider vs domed slider), making often the cut at 170 sqft. This is despite the fact that the distance between line groups is larger on big canopies. In other words, you have the same force pushing on the slider from bottom to top, but more force spreading the lines and therefore pushing the slider down, so the slider will come down quicker and potentially make the opening harder. 2. Large canopies have simply more surface, so they can cause more drag. That means larger deceleration on opening. On a windy day, holding a tiny canopy is easier than holding a massive one. Same thing on opening, a small canopy can slow you down just so much, but a big one will slow you down much more. My point is that jumping larger canopies does not protect you from hard openings. If something, that's the opposite.
  15. I haven't flew the Odyssey EVO, and I have just a few jumps on Katanas, so take my opinion with a grain of salt. Just judging by planform design, top-skin smoothness and miniribs, I would say that the Odyssey is a much better/modern/efficient design. It will probably carry you longer on your swoop, for a given airspeed. It will also probably behave better on rears and have better slow flight characteristics. Openings, judging on videos, are also good. But there is more to a canopy than that. I really have no idea what is its behaviour in turbulence, its "ground-hungriness", recovery arc, etc. Also the resale value.
