I put a cut off zip tie under the place where the front pockets connect to the pack, bounce solved. Yes it does take a good 1-2 hours to get the pack fitted properly, with shoulder adjustments for height, hip belt adjustments, etc. The best way to fit it is to load it heavy (40+lbs), do a good walk for at least 30 minutes, feel where the pressure points on your hip bone are (top, bottom, side, middle) and adjust the degree of the belt for the the proper hip bone via the velro in the back, then do another 10 minutes and repeat until you have no more pressure points on your hips.
As far as swaying, mine do not sway side to side at all. You can adjust sideways sway via the blue elastic loop at the side-bottom of the front pockets.
There are alot of straps, and it takes patience, but once you get it dialed in just right, its wonderful.
It is not bladder friendly because you are meant to carry your water in bottles/platys in the front pockets. Don't give up so easy!
Did you take it on a hike, or just demo in a shop/friends house?
