Bowlingdude300, I bought mine with a 4 1/2 inch pin. I have it drilled pin 1 1/2 inches above the bridge c.g. in line in palm. Nice even reaction devastating hit on the backend. On the desert i stand about 20 middle dot and play anywhere from 10 to 5 board doesn't overreact but arcs very evenly blowing the rack with about 85% carry of the ten pin.......hope this helps you decide what you are looking for........>>>>>>>>THERE IS ONLY LANE #1.
