Layouts Explained

Your Roll, Pap and Axis Shift

What most bowlers do not understand is that not everyone has the same roll, PAP, or axis shift.  For example, the manufactures drill sheet included with every ball sold is a generic drill sheet. It assumes that the person buying this ball has a standard 3/4 roll with a 45 degree axis shift and a PAP of 5 inches out and 1 inch up. 

About Your PAP

However, only about 55% of all bowlers has an average PAP location and axis rotation. That mean almost 1/2 of all axis shifts and PAPs are different, hence the drill patterns will not perform as described and the ball reaction will differ from what was predicted in the layout sheet. The more the PAP location and/or axis shift differ from the average, the more the differences will be. 

Bad Layouts = Bad Results

If you have a ball drilled without the person drilling your ball knowing your PAP location, the amount of rotation your axis travels and your track location, then there is about a 55% chance your ball will be drilled incorrectly for your ball release.

I cannot tell everyone how many times I have seen first time customers bring in equipment that was drilled exactly the opposite of what their layout specifications called for. The bottom line is that just because someone has a drill press does no mean they know how to layout a ball.

On Lane Analysis

If you are a new customer, we DO NOT DRILL a ball for you UNTILL we analyze your ball track, find your true PAP and axis of rotation. We do this by marking you pap and have you throw your current bowling ball on the lanes until we can determine what your axis shift and roll is.

Only after this is done can ANYONE determine what ball and layout you is best for your individual needs and be able to match the lane condition you will bowling on.

Don't Accept Guesswork

If you have had your ball drilled without the above actions being taken, then the person drilling your ball is either guessing or assuming that you have a standard PAP and axis shift and they will be right about 55% of time. For the amount of money you are paying for bowling equipment, being right 55% of the time is just not acceptable.

If you walk into a pro shop and they do not, or have not, done a lane analysis to determine the above criteria, I suggest you RUN out because that person is either more interested in taking your money and/or just doesn't understand the theory of layouts. Either way, you are spending good money with a 55% chance of bad results.
