I need to know your advices concerning the drilling of a plastic bowling ball, for example the T Zone.
Actually I drilled a 13Lbs ball for a friend who uses the pincky and the ring finger because its middle finger is out of order.
Because he has a trouble to make the 10th pin I ordered a 12Lbs T Zone for him but I don't know how to drill it.
Thanks in advance,
Vincent
Answer Just drill the ball with the CG in the center of the grip. The Tzone does not have a dynamic core in it so any kind of lable shift wont make much, if any, difference in the reaction. The balls material will make it a good spare ball. The most important thing is to get the grip correct.
