Thor,<br>I use an Arcteryx Bora 80 for multi-day trips, and an Arcteryx Bora 40 for day/1 night hikes. Although on the more expensive side, I don't regret spending the money. These packs are well made and comfortable. The Bora 80 is fully adjustible, and comes in three frame/torso sizes to accomodate just about anyone. My suggestion to you would be to visit a few outdoor shops and try out various makes and models. Add 30-40 pounds and walk around the store awhile. Then get whichever one/s feel "right". Hope this helps.
