Retaining axis tilt for low tilt bowler.

I was inquiring what is more critical in the layout of a low tilt(7*) bowler’s ball with 40-60 degree axis rotation. Does the pin to pap distance or the angle ratio have more effect on the performance of the drilled ball.
I am trying to see which balls in my arsenal will theoretically perform better so I can cull some of the outliers that I have.
I have read some of the wiki pages and assorted post but cannot definitively sort it out. I was hoping for some insight.
LH stroker
5 3/8 x 1 3/8 up
250-275 rpm
7* at. 40-60 ar
17 mph off hand

Wow!
Thanks
I presume the 14# weight is a non factor.

My arsenal lists are a guideline that defines a good usable range.
Specific ball needs to be considered when choosing a layout. For the most part, 14# equipment won't need much if any adjustments.

I forgot to comment

Pin to PAP and Ratio are used together to tune a layout to a specific release. I don't consider one without the other.
There are actually 3 parts to consider for layouts. Pin to PAP, Ratio and Totals.
The release defined with Tilt, Rotation, Speed and Revs are used to determine the layout.

It looks like most of my ball selection does not fit exactly like you describe, mostly the p2p distances. I have been pretty much shootin in the dark trying to hit the right combination. I think the balls that are close in ratio and sum with some p2p variation will help to begin to deal with this rubics cube of bowling balls. Mostly the balls I have are sym @ 4”or less or at 5”and asym @ 4-4.5”p2p. I have a plethora of balls to work with now I and will be using your data going forward with modification of some old the balls or even new ball layouts. I hope to be able to visually see the reaction variance from what I have in reference to the categories that you have set out.
