Harder to find in the U.S., too. Typical FRC game object--unobtanium.

I would expect bowling balls or anything heavy would add some form of pad under the field to help mitigate floor damage? I'm envisioning a school Activities Director freaking out over the idea of a robot dropping a bowling ball on to carpet that is sitting on his basketball court.

I think that could be arranged. Shape the pad to roll the ball out onto the field, and possibly knock something else (like a cluster of bowling balls) into even more disarray... Hmm, I like that idea!
