For the 33s it's usually better to just put a person on each side, then rotate it to carry it tube face up with a hand on each corner.
29 and below though I've never had an issue (aside from obnoxious ones like the Egret 2 or something with a floating mount). Just unbolt, lean the top towards you a bit, one hand on the upper left corner, one on the bottom right, pop it up a little to get it off the bottom bolts, set on the CP, pull the bottom to your beltline, then pick up and off you go to wherever you're going.
At 29" only 70lbs (or less as you go smaller), you don't need to be a big dude to lift them up and move them around if you're doing it properly.
