I received this ball as a hand me down in 1996. I never had to do anything to the cover except have it redrilled to fit me and clean it with alcohol. My Mom bought The Beast during a Summer league the same year it came out and averaged 180 with it. After I had it drilled for me I used it to average in the 190's. One of the best balls I've ever used. It didn't matter what the lanes where doing, what I was doing, if I could hit the pocket The Beast found a way to strike. I donated mine to the YABA after 4 more years of use.
