The nearer the pin to the thumb hole (or better: grip center!), the earlier the ball will roll. The pin should not get closer to the thumb than the grip center. Declining the distance between the pin and the PAP will change the reaction intensity. 3 3/8" from PAP, the reaction is the strongest; getting closer to the finger holes and your track makes the reaction milder.
Additionally, placement of the CG affects ball reaction, too.
For your problem I'd suggest drilling the ball with the pin 1" next to or below your ring finger, the CG in the palm and the mass bias (a line 6 3/4" long, drawn from Pin through the CG marking) on the left side of your thumb. Should give a smooth, continous hook. A ball with a 1-3 pin to CG distance should be a good ball choice. A matt surface finish also adds to the smooth but strong overall hook motion.
Good luck.
