Update time, I bowled 7 games with this ball over the weekend, and after using the first game to become accustomed to the balls roll, I averaged 218. I found this ball to roll early, and long through the heads , then break hard for the pins. It sounds different when hitting the pins, and sometimes leaves strange pin combinations, Ex. Righty 4,9,10 and High flush 7, 9. Only left 2 ten pins in the 7 games, several people came over to see what all the noise was about. Will bowl league on Wed. and update again later, love this ball so far. Any questions??
