alright to start this off i ahve to say the kinetic pearl is one of the best bowling balls i have ever shot down i got it drill for controllable hook but then i also got it dulled out at eather 2000 abolon or 4000abolon cant remember cause it was 2 years ago and the ball still works on any oil contion heavy oil dry all i ahve to do is on heavy oil realease at 20 board to 10 and on dry i have tojsut do a little loft from the 20 board to the 10 and it still pulls right back into the pocket with alot of strength this ball is the best
