I have been bowling 2 fingers since I started bowling in my adult life. I have bought few balls and had them drilled for my hand. I have radical katana? I think that's name of it but its solid red! Ok wen I have tried to bowl with my thumb the ball feels super heavy and I am gripping the ball cause its heavy for one and 2 I dont want to drop it. How do I transition? Everyone I have asked says I just need to do it. But it feels so weird to me that there is no way anything I am doing is right. Any advice? Or is there anyone that gives lessons that ain't gonna break my bank in the fort worth, north Richland hills texas area that could help me learn and figure out this thumb in the ball.
