I purchased a 15 lb. Gamebreaker back in on Sept. 3rd of this year. and have bowled with it for the last 12/13 weeks. I bowl in 3 different leagues ( Heavy Oil in 2 of the leagues and Med. on the other) and have been subbing in another (heavy oil) for the last 4 weeks. That would give me over 150+ games with this ball, including practice . After every shift I take it to the pro shop to get cleaned. Yesterday, the ball was just skidding and skidding down the whole lane - No reaction - No break - Nothing. I think I have just burned out this ball. This also happened to me with my SR300. I am thinking about jumping off the Ebonite bandwagon and trying something else. Can someone recommend something else for me to use ?
