You might try one of the medium size Alice packs with a frame. My son wanted one for college, not real pricey either.Hangar 18if I remember right we paid $35.00 on e-bay and alot of other places they run $80.00+ without the frame
After looking them all over I think the Long Hunter might be too big and since the Siwash will carry 85% of the LH it might be the way to go. Did you look at the military ones?
Remember they do have a Lifetime warranty on them, that could help justify the costof any of them.
