Educate your hands
I can not (do not) turn my hands over at impact. The result is always a HUGE banana slice. Any drills that will teach me how and when to turn the hands?
A: The best way I know how to educate your hands would be something I picked up from a man named Paul Bertholy. He would ask his students to rotate the left palm towards the sky after impact with the intension of "catching the rain drops". If you can practice that move those banana slices will be a thing of the past and you'll find yourself enjoying banana splits paid for by your playing partners.
