I have this ball drilled with the pin just above my ring finger for skid/snap reaction to medium-oiled lanes. I was throwing it 15-17th board on synthetic 38' med oil with tight backends. It was great! I bowled a 232-237-212 my first 3 official games on it. It hits like a Mack Truck and the backend is craziness, yet not over "the edge" so I can have a little control over it. I did hit a few Brooklyn strikes, but on a scale from 1-10 I give this ball a 9! Great Ball!
