i have had my unleashed for about 2 weeks aprox. 15 games. i keep it the same way i got it out of box, some cleaner ( rev-it). i have not been to happy with the reaction, the ball is a 16# 0oz top weight 2 3/4 pin 2 inches. it does not seem to react at the back end like i want it too. should i shine it or scuff it? or just keep throwing it?
