donny, once it's on any kind of carrier it's not a problem..it's the lift from the ground up/down, especially from the tailgate of my suv that concerns me. I take an old duovox bass amp to my wed jam night for bass players to use, and it's 50lbs including the carrier.. I can handle the lift, but just barely..I will bungee a 12-lb dumbbell to that and try the 62-lb lift. ..and pray i don't hurt myself..then try a 15-pounder... if that's ok then it's full steam ahead.... re the rocknroller: I'm one of those who carries the bare kb under his arm, i believe it's easier and safer that way. I don't mind extra steps..one trip for the kb and x-stand, one trip for the amp on carrier and shoulder bag of mics, cables, etc..one trip for the horns. setup is a breeze..I even leave my power cord/cables in the amp and bungee them to the amp or carrier..then don't have to do anything but stick them into kb..making 3 trips is good exercise, and i'd rather take extra steps than place a ton of stuff on a rocknroller in cases, unpack/repack, find places on the gi to put the roller, cases, etc..and i never have to take the amp on/off the carrier i use..it's all one unit..I just have to lift it in/out of my suv, then roll it around for the rest of the night.
