ha,,, with 55 to 45,,, ball changed from OOB to 1000 grit, a little bit better when the backend is clean, hook 5 board more and 2-3 degree sharp..but still cannot handle carry down well, good when practice, no more than 3 board move, but such in league play because of lane change quickly.
the 75 degree one is only a first arrow straight shot ball.
the class logo make me feel the 'back to the future', ball shape bring me 10 years back feeling.
