I've been working on this particular issue for the last few weeks and I believe I have it under control now. I started cupping my wrist a little to try and keep my hand behind the ball more. Now I'm almost under the ball and am no longer sliding it out there like a suit case.. If I can remember to bring my camera out next practice I'll take another video for comparison. Since I have been doing that I have not had any more issues with it tracking over the thumb hole.

Although the only caveat that I am seeing with cupping my wrist is that it is causing me to have a lot more hook and causing me to play further left. Which in it's own is fine I can play anywhere on the lane that I need too, but I am losing my pin carry. It's kind of hard to explain, but when the ball hits the pins it's like the pins just fall over, there is not any mixing going on. Does that make sense?

If we could see what's happening, it would help a lot. It could be technique or it might even be how you're getting lined up. Hard to tell without seeing.

Yeah I figured that.. Like I said I'll go out and get some video next time I go out to practice.. Unless I can talk the wife into video taping league Saturday. Although I did just take my ball in to the Pro Shop for a rejuvenation/resurface.. It just might have been a case of an oil logged ball that lost it's energy. I guess I'll find out tomorrow.

edit: When I do my next video for comparison would it be easier if I didn't wear my wrist support? I prefer to wear it, only because if I don't wear it my wrist is killing me after about two games. And it definitely helps with the pain.

Do whatever you normally do when you bowl.

Well i just came back to the Pro Shop and had my ball polished and asked the pro to take a look at what i was doing. I was basically just rolling it. After cupping my wrist more and making sure to turn the issue was solved, man the ball hooked like crazy. I also did feel a little more sore doing this and I feel like I can't get quite as high with my back swing when my wrist is cupped as much. Probably will just take time.

Well the rejuvenation must have helped.. I now have pin carry again. My ball hits like a freight train again... now if I can just figure out what line I need to take on my new ball.
