While I'm not particularly familiar with the Ascent series, I do have two other Camelbaks, the HAWG and the TransAlp. Both are quite well constructed, ride well on the back, tend not to shift around alot, and have easily withstood the moderate amount of use/"abuse" that I've given them.
The TransAlp is probably the closest to the other Ascent series packs, and I can say that it has a pretty effective strap and suspension system, has a good amount of adjustability, the the amount of pockets, slots, and organizing is very good. A place for everything, and everything in its place. Without water and a load, it seems "heavier" than it should be, but that's mostly due to the rigidity given by the extra padding and layers necessary to separate and insulate the hydration bladder from the rest of the pack. My only caution would be to not try to overfill the bladder, as it tends to "round out" the bladder, and the pack feels as though it might roll from side to side during strenuous movement, leaning, and bending, until the water level decreases from drinking. For my own uses, I'd like to see provision for adding a small pocket or two to the fronts of the shoulder straps for smaller incidentals, such as snack bars, a compass, a folding knife, etc., but the pack works quite well right out of the box for me.
