i haven't posted an official review on this ball yet as i haven't had it that long. however, i love the reaction i'm getting out of the ball. i have the pin next to my ring finger, the cg is swung a little to the right, and the psa is below the thumbhole. there is a balance hole down in the right thumb quadrant. more importantly, the ball has been finished with a 1,000 grit abralon pad and a coat of brunswick polish. this ball really defines skid, hook, and roll. i can't place the pin under the fingerholes as i track too high( pap 5 7/8 by 3/4 up ).
