Left handed bowler... minor arthritic distortion of fingers, but not major. My current lateral finger requirements are 1 inch left on ring and 1/8 LEFT on middle, way off the norm. It seems to me when I rotate my hand that adding right lateral thumb would move my fingers to the right as well. True? Opposite? I've looked quite pitch videos recently and no one mentions any relationship in this area. Myabe it's my imagination?
