Joe,
Is it true that a hook rolls more than a slice because a hook has overspin?

Hello Spud,
Anyone who has ever played ping pong knows if you put overspin on the ball it will dive down quickly, and in golf that is known as a duck hook, so overspin is not the answer. The ball must have a little bit of underspin in order to stay in the air longer, and you can also prove that with a ping pong ball. There are two reasons why a hook rolls more than a slice. First reason is a hook has less underspin, and the other reason is that the clubface must strike the ball in a more closed position for a hook, which means less loft and lower shot trajectory than the slice, which has a more lofted open clubface position. As a result, the lower hook is likely to roll more than the higher slice.
