So I actually went way out to left field and picked up a Gregory Z55. Its a little smaller than the Exos or REI but I wanted to keep right in the middle of 3-4000ci if possible. The Medium Z55 is at 3350 which is pretty darn close. I figure if I can pull of a weekend trip with a Kestrel 38 (2200) then I should be able to pull off a week or more with 3350!
I havent taken it out yet (just bought it yesterday) but I love the fit; also there are not a lot of bells and whistles, which I like. Its 3lbs 5oz which is a little heavier than I wanted but if you remove the lid it takes it down to a little less than 3lbs. I tried out a Granite Gear and GoLite but I just didnt like the lack of suspension, it just didnt seem as bombproof as the Gregory. Either way just an update on the subject I started. Thanks for everyones advice and I will chime in after I take it out for a trip.
