I am getting back into bowling after being away for 15 years.  I have a Columbia Detour, Storm Tropical, Columbia White Dot for spares,  and just picked up a Columbia U-Turn Reactive on e-bay.   I have a good pro shop that I use to drill up my equipment.  I asked him to drill up the U-Turn more aggressive.  I would like to post a review, but my knowledge of drill layouts is limited.  The U-Turn was drilled with the pin under the ring finger and the CG to the right of my palm (I'm right handed).  There is a weight hole drilled.  How do I describe this layout.  I have seen so many descriptions (i.e., stacked leverage, 4-1/2 x 3-1/2, etc.) and would like to know how I can describe the way my U-Turn is drilled.  Thanks for the advice!

Did your proshop find out where your PAP is?  Finding that location is the starting point for describing the layout used on the ball.

My pro shop did not measure the PAP.  However, he has seen me throw and is familiar with my game.  I hope this isn't a stupid question, but how do you locate the MB point.  I am guessing this means the mass bias point.  Can I measure the PAP myself?  If so, how.  I really appreciate the help you are providing.
