Bashing tops against eachother is always good fun. ^_^
There didn't seem to be any specific strategy to being out of control, though. Touching the other top does as much as them touching you, so just maxing out spin and balance, then trying to touch the other top before it charges up seems to be the only way to go. It's a bit hard to tell who won as well, since the game immediately restarts. Maybe there's an input we're not noticing?
