While this may seem like a good idea on the surface, you need to remember this: Back in "the old days" of urethane popularity, most balls had the pin in the label area.

 Nowadays, even if you drill a ball over the label, most likely the pin will be at least 2-3 inches away.

 And another thing. It isn't always the pin position that makes a ball condition specific. More likely is the surface of the ball and the volume of oil it was designed to handle.
