I will second the suggestion for the Eberlestock pack. Although I dont own one myself, I will as soon as I save up the money. I looked at the pack last year at an Outdoor Expo and fell in love. It is the most versatile pack I have seen, and the most comfortbale I have tried. I am 6'8", so most packs fit me weird, and usually a bit uncomfortably. THis pack fit perfect. My father in law and brother in law, who are both around the 6 foot mark, agreed that it was the most comfortable pack they had tried. At the demo, they had the pack loaded with 100 pds., just so you could feel how the pack felt with a lot of weight. The pack held the weight well, and seem to distribute it better than most packs I had tried. Although I usually wouldnt pack out 100 pds. at a time, with this pack I would at least have been comfortable trying!
