I'm sure it has been discussed here in depth, maybe it hasn't. As I understand it grooves themselves do not impart spin to a golf ball. Their sole function is to channel moisture and debris away from the ball and clinics interaction. I can understand that theory but I have a question then... if the grooves have no impact then how do we lose spin as grooves wear out? In theory the depth of the grooves should be unaffected by use which shouldn't block their ability to channel junk away. So why do they wear out and lose spin?
