I'm really picky about that stuff. Some of them just feel wrong and I can't shake the discomfort. I've had a typical camelbak and they make my lower back ache after a while. That's my fault for having a weak lower back, but still.. I've tried two hip belts, the Dakine Hot Laps and the EVOC something or other. The Dakine has a 2L bladder. The EVOC has a small bladder and holds a bottle on each side. My preferred setup for the hip pack is the EVOC pack with the two bottles and no bladder, plus a bottle on the frame. Rode thjat set up for a year or so and liked it well enough. Minimal bounce. I prefer bottles to bladder. The hose annoys me and I don't mind slowing or stopping to drink.
They both need to be cinched down fairly tight to not bouce and the tightness isn't real comfortable, but still better than a camelbak.... until recently. I recently got a Camelbak Skyline. Love it. It's a pack on your back but it sits really low. Almost like a bigger hip pack but with shoulder straps. I've been on a dozen or so rides with it now and it's my favorite setup of them all. Hold more than a hip pack, feels way better than a typical camelback
