I bowl on Tue,Wed,Thu at 3 different houses. Avg 220, 215, 195. Bowled 12 tournament games in one day on dryer lanes with weak back ends. Wrist is sore, so I added my Gizmo and decided to change my philosophy. Changed from trying to make everything perfect, exact timing, exact line, perfect release and break point, to the old Golf adage of Grip-IT and Rip-it. Looked at my mark, walked to the line and gave it all I had to give, speed and revs. Shot 714, 710, and 700 respectfully. Guess I will ride this new method until it quits on me.
