Ok, recently bowled in a local tourney and cant seem to do much. I got rid of my rotogrip sd73 classic, and bought a storm special agent. It seems to have much better back end for me. I bought it after having a bad tourney, my other ball, a ebonite crossover does ok, but i need something even stronger.I am a left handed bowler, and when my ball doesnt hook i cant seem to do much. I use a 4 step approach with a very rhythm like approach. Would 5 or 6 steps help? I have tried moving the ball around in my swing to create more revolutions as well? any thoughts or observations would be appreciated!
