Technically speaking, it is a different DA layout for each (unless they happen to all have the same PAP).
You are absolutely right Sir. PAP plays a huge role. DA may be the same but it makes Pin placement different for different Bowles. But what about when one particular bowler puts the same layout on all his balls.
As I understand, and I may be wrong, the Drilling angle determines the skid phase of the ball, but so does the coverstock.
A polished ball vs a mate finish.
Secondly. The core dynamics also play a role in how far the ball goes down before it pick up.
High vs Low RG.
And last but not least, the hand position.
Up the back vs on the side.
So how come one particular Bowler with his unique PAP throws all kinds of surfaces and RGs, drill all balls with the same DA or PSA layout and keeps striking?
I do know that THS is very forgiving some times but PROs also have favorite layours which they use on all balls. Sport patterns and PBA patterns aren't as forgiving as the THS.
I'm not arguing here just to argue. I have very little knowledge and I'm trying to learn. These are the few questions which happened to pop up in my mind after you post, so I asked.
Some here advocate universal layout on all balls as well.
Please educate.
