Thanks for diggin it guys!
I'll just go ahead with the 2-piece, then. If more people want a single-piece I might do it in the future, but the 2-piece makes much more sense for now. I'll also do up a little strapping diagram to accompany its release, like where to cut the holes for the straps to pass through.
I'm just working out the kinks, the leg is a little more complicated than it looks, there's a couple extra pieces I'm trying to figure out how best to attach.
Ral - I was thinking of unfolding myself but if you're offering an unfold I think I'll take you up on that, I like yours better than mine...
