I would also say that optical is the only way to go. What I can't understand is why I saw a ball mouse for sale the other day which had a red LED on the bottom to make it look like an optical mouse. The package boasted of the "cool optical look, without the price", but with the cheap opticals running for $10 there's no reason to every buy a ball again.
