I'm not sure if my opinion is worth much to a high average bowler. I have a 170 average. Slow-medium ball speed. Anyway, I love the ball. I had it drilled #5 on the Ebonite drill sheet. Not having much speed, I wasn't getting good carry, so I polished it lightly and that did it. Only had two
10-pins for the series. I bought it to combat carrydown and it does that, but also works for fresh oil, no carrydown.
