I know there are a bunch of threads on this pack, but I recently got mine and figured I would throw my 2 cents into the pot. I had been drooling over this pack for a while, but when taped seams and other nice improvements like the newer side straps and such, I just had to have one. That, and I had already read a lot of good things about it on here and on blogs.
My first impressions are that I am very, very impressed. Can't wait to try it in the field soon. I got Joe to do a mod that I thought would work out well--two smaller center pockets rather than one--and I think it turned out great. Seems like it will be easier to organize and find my gear on the outside of my pack.
