Sorry about that Chun. Hehe I don't get much time on the weekends to come on here. I would actually have to agree with what Jeff said. Place the pin underneath your middle finger, this should give you a 4 1/2" pin to pap, but put the MB logo on your Vertical Axis Line. This should get you good length and get the ball to roll strong on the backend, but not over-react.
Thanks,
