I actually did learn a lot. That is why I said why adjust surface on a THS. Sport patterns, yes I can see regularly keeping on top of surface. And if I knew I was going to be bowling on heavy oil, I would adjust surfaces. But on a regular ths league where there is defined friction to the outside, I still see it as unneeded AS LONG AS THE EQUIPMENT IS STILL WORKING. And providing the bowler is not on a skill level 99.9% of us will ever have a hope of reaching. Maybe the issue is that, in every house I bowl at, I get my best reaction at roughly 4000 grit and slightly polished equipment, which is where the surface scans show a ball ending up at in that video. I doubt the factors that effect those numbers will change it too much. If I use equipment at a lower grit, my balls start burning up by the end of the first game. If I go higher, I lose the control I need. Also, if I keep everything at the same grit, I can control reaction shape and strength with ball choice and drilling.
And Good Times, there is no need to be condescending all the time. I'm here to learn and try to understand the game better. When i am wrong, which is frequently because I don't have a full understanding of the theoretical side of bowling, I welcome people saying "hey this is where you are wrong," and correcting me. What I don't welcome is someone saying "you didn't learn a single thing from all those excellent responses, did you?" Or whatever you said, without actually answering my new question which was different from my first question because of the answers I received. You sir are just another dick behind a keyboard trolling the Internet for fun.
