i'm in the market for a new pack and i have done some pretty extensive internet research and have narrowed it down to these two packs. i wanted something under 5 pounds and between 3500-4000 ci. and these fit my criteria. unfortunately i havent made it to any stores to try either of them on, so i'm waiting to make my definite decision untill then. if anyone could provide feedback, it would be greatly appreciated. thanx
