I drilled mine with a Pin  5 1/8 from  the PAP

4 1/8 pinn from the CG

 

I  used it with a 1000 Abralon pad and the ball is really clean in the from and much more back end than ever anticipated.  I used playing different angles in or out on a medium sport pattern. Works great from both angles. Very versatile. I am going to drill one with a shorter pin next to get a bit earlier reaction. I will advise when this is done.  Ball is big bang for the bucks!!!!
