I'm only 13 years of age, and have just started to bowl with Track. I throw a 90 degrees angle, and about 10-12 revs, throwing about 14 mph.
I got this ball, wanting a ball for light oil. Whenever I threw it on light oil, it broke early, and hard. I would throw it 40 feet down the lane, about the 5 board, and it would come back, and hit right on the head pin. I talked to my pro shop owner, and he resurfaced it, and shone it up. Now it will only hook on dry lanes. The problem was, the pin placement was 1/4 of an inch. When it was shone up, I have gotten some good scores on dry lanes. I recommend this ball.
