Last month I rolled a record breaking 247 which is over 30 pins higher than my previous high game. Although I’m still rolling a 12 pound house ball straight without any hook on it before I was just rolling the ball in a straight line from the center to the pocket and now I roll the ball in a straight line from the side to the pocket. This allows the ball to hit the pins at a slight angle which gets more pin action and more strikes. If you’re throwing a straight ball I recommend you try releasing the ball next to the right gutter when you bowl with your right hand and next to the left gutter when you bowl with your left hand. That way when the ball does hit the pocket it will do so at a slight angle and increase your chances of getting a strike.
P.S. Today I set a new left hand record with a 170.
