I Drilled my High Rev Pin Axis and i absolutely love it. I needed something that didnt hook at all, and new if i drilled this ball any other way it would have been more movement than i was looking for. Basically for the guys dont that know what pin axis drilling does, basically it enables you to square up on shots, and not get any over reaction out of the ball. This ball doesnt roll out at all, and stores so much energy, hits the pins like a truck. Defintely a drill pattern only for those with above average revs.
I put my pin right on my PAP 5 3/4 and an 1/8 up.
