all BASE PCs are non-collapse-able? Also, sliders arn't build to be "stowed", correct? Thanks.

just to clairify I am asking this as I have come to know these are "performance enhancing" type things skydivers do to their canopies to get that extra little umph. It seems these kind of things would be skipped in BASE where the integrity/durability of the canopy comes first.

You are correct.

BASE PC's are non-collapsable. The purpose of a collapsable PC is to reduce the amount of parasitic drag on the canopy thus increasing speed and improving performance. In BASE this isn't a problem, and the complexity of a collapsable PC brings risks into the equation that we'd rather leave to the relative safety of the skydiving arena.

Sliders are typically not collapsable for some of the same reasons. Most BASE jumpers use larger rapide links so even if you could collapse the slider, you would not be able to pull it past the links and bumpers.

As a rule in BASE, if it is complicated and there is a more simple way to do it, we choose the simple way. Simple is safe and reliable. Too many moving parts increase the potential for a rigging error or a malfunction.

cool thanks dex. That's what I thought, but you know its always healthy to check it out just in case
