Wish I could give a glowing report like the previous poster, but for me this ball has been anything but good. Mine is drilled 45x3 3/4x30 with a hole. I have tried it at OOB, 2000, 1000, 800 , 500 with polish. Nothing seems to work. I just cannot get a consistent reaction out of this ball. I pride myself in being able to throw just about anything and finding a way to make a ball work. But, this one has me perplexed. I guess it's true that sometime you just don't match up..... for me it's the Score.
