Everything is a trade off.

And so it is with casters. For 99% of the time in FRC, they suck pretty bad, but that 1% they offer something that overcomes the suckiness.

Now that folks think steel Ball Transfers are legal, has anyone used them on a FIRST robot? Tips please?

FYI, in my case the are competing with feet that are currently Delrin but if I don't go with these ball transfers, I am probably going to use UHMWPE -- the best thing I can think of for a slippery foot if I don't go with moving parts...
