Ok fellas... the remainder of the seminar video's are up.. Sorry I didn't get them finished before the weekend but they are done now. If you ever wanted to know about bowling balls and learn from the best, this is your chance. Keep an eye on our you tube page because I will be putting up video's all the time. In the very near future (before the weekend) get up a special interview with Hank Boomershine and featuring the Cell. Also I have some examples of the ball being thrown. You can see the ball in action by a Cranker, a tweener, and a stroker. If you want to put some video's of yourself throwing Roto Grip products we would love to add you to our favorites. let me know if you have any..Thanks and enjoy!
