  1. Interesting read. Id never heard of slider type and choice being a huge factor. It was always about untwisting brake lines and proper line stows. I would assume though that slow sliders would have lower tension knot frequency than faster ones but the data doesn't show a statistically significant difference according to the paper. Also , would using direct control help mitigate some of the risk? Given the fact that the paper doesn't mention it I would venture there isn't much of a statistically significant difference there either. As always with tension knots. I have more questions than answers as time goes on. But maybe that's not such a bad thing. According to the paper, the whole link between the Hayduke and tension knots wasn't based on anything concrete statistically speaking. I really hope someone who made those connections would chime in so we can ascertain what is what.
  2. I always thought people made too much of the "Made in Vietnam" angle, but from what you say it could potentially be a big deal. Like "life or death" big deal. Would also be interested to know and understand the evidence linking the Hayduke to tension knots, because all I have so far are discussions between some BASE jumpers I met in Brazil. Look forward to that white paper, but the whole idea so far has been that this is a design issue. If there is a design issue, and on top of that improper rigging , that's not a good look for squirrel at all. Did you report this issue with the Outlaw to Squirrel?
  3. Was that the reason they did that? In their newsletter they mentioned something about a reliability study containing data of about 40000 jumps that led to the Hayduke 2. When I was in Brazil in Jan, some people were saying a disproportionate number of tension knots were linked to the Hayduke, and that squirrel was planning an upgrade. Of course I dont know how much of it is true or what evidence it was based on , but if there is something to it, it would be interesting to know which new features on the Hayduke 2 were added with the express purpose of reducing tension knot occurrence and/or severity.
  4. Thanks a lot Tom. Your advise really helped clear some stuff up. Really appreciate it.
  5. What made them opt for that design? The reasons you mentioned above? About the different line weights triggering more opening shock on those lines etc? I have an apex container and canopy(Summit and Flik2), but I was wondering if maybe getting a different canopy would be better for slider up openings and slider up jumping in general. Continuous lines and ZP on the nose seem to be the main differences, and Im not sure whether its worth making a change. Apex has a blog post on why it doesnt have ZP and it made sense. But once again, they seem to be the exception as Atair, squirrel and adrenalin all use ZP on the nose. I know the spectra lines are another point of difference but nobody really talks shit about dacron so thats not really an issue for me.
  6. Thanks for the answer Antoine. I think from speaking with BASE jumpers with way more experience than me, the consensus seems to be that there is no definitive solution, or even an indication as to what a solution looks like, with respect to tension knots and canopy design. I just thought it interesting that 3 of the biggest BASE canopy manufacturers use this approach. I was thinking about putting together a slider up specific rig and while going over the various options, this pattern emerged.
  7. Hey dudeman17, with all due respect, lets keep it on point. This is not a post about who should be base jumping and who shouldnt, or whether complacency kills. If you would like to address those things, please create your own post. Lets not go off topic please. This post is about the link between continuous break lines and tension knots. Thats it.
  8. Thanks for the response Tom! Any theories as to why squirrel, adrenalin and atair all decided to go down the "trunk and branch" route?
  9. Hey guys, Just wanted to get different opinions on the link between continuous control lines and decreased tension knot risk (both frequency and severity from what little I read). Atair, squirrel and adrenalin all use these lines and specifically mention that it is for the express purpose of lowering tension knot risk. Apex, on the other hand , say they have no evidence continuous control lines reduce tension knots. As someone who jumps apex containers and canopy, this is something I wanted to understand better.
  10. Does the pocket slider completely solve the issue? I swear I read somewhere on this website that a dude was getting very hard openings even with the pocket slider. The thought did cross my mind.
  11. The Pilot in question is actually bigger than my Sabre2 (170 vs 188) so I thought the upsize might work in my favor. But it looks like the consensus is with the Pilot7, even a smaller one. Thanks.
  12. I have a Wings W13 and it currently holds a Sabre2 170 loaded at 1.3.I am looking to get into wingsuiting. My experience with the openings from both my packjobs and those of several others does not give me much confidence for use with wingsuits. My container has all the wingsuit modifications and I also have ordered a semi stowless dbag which is on its way. First, does a Wings W13 (which holds a Sabre 2 170) hold a Pilot 188 ZPX? Aerodyne says that a Pilot ZPX packs similar to a regular ZP for the first 100 jumps and then "somewhat smaller" after but still not as small as a Pilot 168(even though their website says ZPX has about 20 percent smaller pack volume). According to Sunrise, a Wings W-13 fits a 170 ZP and no more but they said that a Pilot 188 ZPX "would go in there". Those two seem to be conflicting. Does a Pilot 188 ZPX pack larger or smaller than a 170 Sabre 2? Also, what do you guys think about an average skydiver using a Sabre2 loaded at 1.3 for wingsuiting? Finally, would the Pilot 188 ZPX be a much better choice than a Pilot7 167 ZP (there is one for sale that I think fits my budget) or a Spectre 170? I prefer to buy used.
