i walked into kmart today and they had bowling stuff and the had this ball called the magnum and it was in pearl and the had one sanded and it said it was made by ebonite and have also seen a renegade made by columbia at dunhams, so i was wondering are these balls just like a tornado and white dot? why don't they just sell tornados andwhite dots? are these balls even made in the same factory as all the other balls from columbia and ebonite?
