It just sounds like you're trying to over-complicate things. It's a typical point of progression for most pro shop guys, you want to know the technical stuff so you can feel like you know what you're doing, but the more technical stuff you know, the more you realize simpler is better. It's nice to know just to know, but the game needs less math and more personal vision and feel. I can take one ball with one surface and one drill and make it do 7 different things, I don't need 7 different balls with different surfaces and layouts to make up for my lack of skill and/or versatility. Bowler skill > math any day of the week. Understanding how layouts affect ball reaction is definitely good information, but doing abstract things so you can feel smarter is just taking something simple and making it complicated for the sake of ego really. Not trying to be mean or dog anyone, and I'm not insinuating that you're an egomaniac on a trip, just saying that's where it leads.
