The thing about the multiplier balls is that it seems pretty easy to push them off, while if you got a good grip on the bar you would be practically immovable. You'd get knocked around a lot, of course, but you'd stay on.
If you could make a multiplier manipulator that could grab the bar too, like animater31405 said, you might do *very* well. I think the key in this competition will be doing a lot of things with the same part. If you try to make a separate mechanism for everything, you'll end up hitting the size/weight limit about a third of the way in. If you try to specialize, you'll come up against an opponent who can defend against your particular strength.

know someone will show up at regionals with a robot that whacks hanging bots with a baseball bat. LOL, piñata time!
