I have one ordered ,a 6300 roll top with base talon, vx 33 multicam. I have been using a Gregory for 15+ yrs. and anything over 60 lbs. is unfun. The belt on the Gregory does not stay put ,and I think the lumbar pad could be the culprit. Frame stays and such on the Gregory seem to start "collapsing" after 60 lbs.and there seems there is no way to get it to ride comfortable.
