I know that most of us who were at Big River in June helped load several of both. I personally assisted, I think with Omar actually, 2 or three with winches and a few more with bars. Didn't notice either one being "easier". Mine was the worst of the bunch of floater bars, backed too far in (Brad got the workout on that one!). But the winches didn't seem to help or hinder, IMO, still the same routine and just as much time.
Launched and loaded mine with the floater solo many times with little problem.
