If I eventually get a cramp in my left hand what's going on? Do I need to lighten my "Grip of Freezing Death"? I don't think it's conditioning because I play other times for hours on end. I'm talking about after a minute and a half. Also, does anyone know how to build up economic movement? I feel sometimes that my hands are flying all over to get to a destination. It probably adds some pizzazz, but I see a lot of accomplished guys (Michael Angelo Batio) and they barely move their hands.
