Re: [vid666] Internal handle pilot chutes
In reply to:
...I PERSONALLY, and from my limited experience think that if you want to jump a big PC handheld at a low (not super low - no experience/opinion) alti, and get the canopy out fast, you should leave the ZP material exposed
I certainly don't think you ought to leave it in a mushroom. I see people using this kind of technique all the time (taking the mushroom out of the BOC and just holding it directly). In my opinion, it's ok for longer delays, but for very low airspeed (like go and throw) jumps, it's just asking for a hesitation. My experience has been that both stowed go and throws and handheld mushroom go and throws experience approximately the same hesitation rate, which I'd say is about 1 in 20 (for a noticeable hesitation).
I'm not a fan of the "leave the ZP out" technique either, because I think it can make it harder to pitch the PC to full bridle extension. But I certainly think it's less prone to hesitation than either a stowed jump or a hand held mushroom.
In reply to:
I would just imagine that by having a longer bridle one places the PC further away from the burble ( which is the reason why BASE has been using longer 9ft bridles in a first place)
I think that the primary reason to have longer bridles is to generate more snatch force at low airspeed. Initially, I think this was an effort to combat the greater pull force required to open a velcro rig (versus pins).
The burble from a subterminal body is nowhere near 9 feet. It's not even close to 6 feet. You don't need that much bridle to escape the tiny burble of a slider down BASE jump (remember that the size of the burble is proportional to the fall rate--it grows to full size only at terminal, and at a zero airspeed [exit] it is non-existent).
