  1. Here is what happens when the oxygen flow is not adequate ...: http://www.youtube.com/watch?v=tXa4w4aYKEk
  2. What about the same scenario with magnetic riser covers?
  3. That's not the point. See this: http://www.sendspace.com/file/f7cr59 Read this: http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=2101957
  4. Vector now has a 3rd version of magnetic riser covers. Do you know which version they had?
  5. Is Icon available with Skyhook?
  6. I think it is safe to assume that Dacron is twice as bulky as Spectra, and adds from half to one pack volume (as in "next canopy size up"). See this document for Spectra vs Dacron pack volumes: http://www.pia.com/piapubs/TSDocuments/TS-104CanopyVolume.pdf
  7. Try E-bay. I once bought 20 years of Parachutist, and 20 years od Skydiving there, cheap.
  8. Hehe, I pull at 3200 feet. Takes up to 1000 feet to open
  9. I relined my Spectre 190 with Dacron (used to be lined with Microline) - I can definately feel the difference! The slider descends way slower. Love it!
  10. Nylon – 30 to 35 % Polyester (Dacron) – 15 to 20 % Spectra – 5 to 9 % Technora (HMA) – 4.6 % Vectran – 3.3 to 3.7 % Kevlar – 1.0 % Sparky Are we talking stretch or elongation? "Stretch is the elasticity of a line, and the line returns to original length after deployment forces are reduced. Elongation is the more permanent lengthening over time from loads being imposed on the line."
  11. Sparky Hmmmm, read the whole story from Bill Booth: "Again, if pillows are so bad, why are they used as cutaway handles on 99% of the rigs out there?" Although I designed the "soft pillow" handle for the 3-ring release in the first place, I won't get into the discussion (too much) about whether it makes a good reserve handle for freeflyers. Most decisions in skydiving are tradeoffs, and this is certainly one of them. However, I do think a pillow makes a better cutaway handle than a reserve handle, simply because, where the pillow is in a cutaway situation, is much different from where it is in a reserve pull situation. Think about it. In almost all situations where a cutaway is needed, you're hanging from your main risers, and your main lift web, where your cutaway pillow sits, is pulled up and away from your body, so your cutaway pillow is literally right in front of your nose. Now think of where your reserve handle is in a total malfunction. It's down below your armpit, tucked tightly against your body, maybe even UNDER the webbing, and more than a little bit hard to see, especially if you're wearing a full face helmet. Now think how much a reserve pillow handle feels like your harness, or a fold in your jumpsuit, especially if you're wearing gloves. Now picture yourself low, out of time, and in desperate need of a reserve handle that you can't see or feel. Aren't you glad you bought that Cypres?"
  12. Does that imply that sport vectors have a seperate serial numbering from military vectors, student vectors, and tandem Sigmas? The ad focuses on sport Vector (pistures), what if the rig number 50,000 falls into a mass military order? Hiw not the serial numbering system work (sport vectors, military vectors, student vectors, and tandem Sigmas rigs)? Seperate numbers, one poll of (shared) numbers????

  15. It will not fit, as per the UPT chart (see attached).
  16. Jumpshack offers a metal cutaway handle. The downside is that it it heavy, so if it is out of pocket in freefall, it will pull the yellow cables out (since there is a very little tension between cables and the loop). The standard cutaway pillow is lightweight, so the probability of that happening is lower.
  17. Vector RSL is different, and the metal cable does not get kinked (the RSL ends with a reserve pin, unlike other rigs, where the RSL pulls the metal reserve cable at approx 90 degree angle). Therefore, it will not be a problem with a Spectra either.
  18. So the big Optimums are available now?
  19. You made an incorrect assumption that I am talking about myself and my gear .
