Ive had my Black Hammer 2001 for two weeks now, and man, i love this ball. They say it is for medium to oily lanes, but ive bowled on every condition and it slams the pocket on all of them. All i have to do is the usual adjustment of where i start my approach, and the ball just does the rest. My average score has went up about 30 pins, Yes! Im having so much fun with it. No real complaints about it.
