I was just wondering about the PAP article which I have read... Based from my understanding, one's PAP is measured or is based on the type of release a bowler has... If the bowler has a low track, PAP would be nearer to the grip line, hence the driller would drill your ball according to your PAP, ryt?? But what if, the specific bowler, would change his shot or the way he releases his bowling ball, would it mean that the ball would not be suitable for him to use??
