I have two packs...an older gregory baltoro 70 which is much too heavy and an rei ridgeline 65L which is lighter but too small on volume (I doubt the 65 L claim). Both packs are comfortable for me. I'm looking for something about 3 pounds and 65 - 70 L
I've been looking for something with a good volume that is around three pounds but I have a couple of special issues. First I don't want something that uses a foam pad as the padding or "frame". I am a hammock camper and I don't use a pad. Second, I need something that will hold my bulky hammock gear. My hammock is a clark tx-250 and its about the size of a football. I use a top quilt and and under quilt instead of a sleeping bag. Combined those are about 16L after being compressed. Third I'm not a big fan of strapping gear to the outside of my pack ... I'll do it if I have to but I'd rather not.
I am not an ultralighter but i have always been a light weight backpacker. The hammock gear is also a little heavy. I has pushed my total pack weight in the 30 to 35 pound range. The 6 pound gregory pack just weighs too much of that no matter how comfortable it is!
Normally I don't need help selecting gear but most of what may be appropriate for me is available by mail order only and that's why I'm asking for recommendations. Things I've studied online: Golite Jam (35 lb load is too much -i'll always be at the top edge of load rating), Golite quest (maybe but many reviews of poor durability for golite packs), rei flash 62 (maybe too small in volume -otherwise ok for price), ula circuit (best option I've found if my gear will fit, pretty expensive), gossamer gear mariposa (nice but better for an ultralighter)
