How do your measure your PAP? I understand it is different for every bowler, but, I really don't know how you find it. I have some new balls that I want to get drilled; but, I would like to have a little more input on the drilling put on them (I am going to be using a different driller than I have in the past...I'm going to have everything done fresh [span, pitches, etc.]). I know my driller can find it, but, is there any way to figure it out myself? Thanks for the help...
