Re: [jonmurrell] What's the latest favorite of these 3?
Well I stand corrected.

My friends Helium is made of parapack, and he wishes he got a cordura rig since he mostly jumps slider down in rugged conditions. Apparently, you can get them in both fabrics. Morpheus makes some really nice gear, and so does APEX, and Marty's gear at Asylum is as stated: "nylon art." I agree with John, get what you like the most, and will suit your style of jumping.
BTW John, your rig and I had a memorable time in Moab.
