[pct-l] Z-Pack Question

[treerings at gmail.com]

I'm considering the ZPacks Dyneema X Gridstop backpack, 3,200 cu. I
currently have a GoLite Pinnacle and a base of 7-10 lbs. Can anyone comment
on the comfort/workmanship/durability of the ZPack Dyneema? Their normal
Cuben Fiber material seems to make a good "disposable" pack, but I want
something more durable. That's why I'm considering the Dyneema option with
them. Many thanks in advance.
