I saw a video on YouTube of someone throwing a perfect game by lining up just to the right of the headpin and having slight curve inward. But has anyone thrown a 300 game using a real extreme curve? i.e. in the middle with heavy right to left draw? I'm a real bowler and I still haven't been able to perfect this. It almost feels like more strikes occur when you throw less hook on the ball. Opinions? Thoughts?
