I'd say unweighted since a: the distance the paddle travels is relatively small and b: the chances of you needing the paddle against the wall (where it would end up if you let it free spin in one direction) aren't very good
Correct me if I'm wrong but doesn't the game use potentiometers as opposed to optical encoders?

Minwah posted while I was typing. Thanks for the confirmation from you and URebel that they are indeed pots. "Non-limeted ones" though, I'm having trouble wrapping my head around that one. Can you point me to that discussion?
