I drilled my Roto Grip Hustle Ink stack leverage. I wanted to the ball to read the front end of the lane smoothly and transition well in the middle part of the lane. I wanted the Hustle Ink to come off the corner with great strength and create great pin reaction.
What I got was a ball that reads well early, transition well through the middle and when the ball comes off the spot it reacts so strong and smooth that the pins stay low causing great messengers and great pin reaction. I have carried more 10 pins with this ball when I hit a little high, a little light and even in the pocket. The ball is so forgiving and it amazingly reads all parts of the lane awesomely. This ball does not over react but if not thrown correctly it can under perform.
