John, I'm sure you are probably right about altering the ball. Upon further reflection, I'm sure my third game struggles are mostly due to a physical (and possibly mental) breakdown on my part. I think I really just want to buy another ball, preferably a more high performance, aggressive ball. But I'll probably hold off. I try to move right in the third game, but I my ball still goes straight. I don't know if the oil has carried, or what, but it doesn't seem to work that well. Maybe I just need to play straight in the third game. I'll have to work on it.
One problem that I'm really struggling with is my thumb beginning to stick midway through game 2. I start to get warmer and sweat, and I think my thumb might even swell slightly. But, when I use some easy slide on my thumb, I drop my next couple of shots. Any suggestions on how I should fix this?
