Mine keeps evolving. I used to have a big back swing, trying to muscle the ball, also causing me to rush approach. Fast ball with little revs, plus inaccurate. I've slowed down my approach, lower back swing, increased the follow through speed, increased speed AND revs, more accurate. I use a wrist device, but I will eventually work on not using it. I figure when I start hitting a couple of 800's, 300's, win a few local scratch tournaments, then I can finally settle in my form/style.
