I have the fast break 4 bag from Ebonite. I like it very much compared to my columbia300 4 ball roller. I think my ebonite bag is easier to load into my trunk as compared to the columbia. FB4 is easier to roll around crowded bowling centers, I know I sound like the advertisement. The large wheels make it easier when rolling over steps, curbs, etc. Sometimes I don't put a ball in the top compartment. It does make it noticeably heavier, and besides there is no need for 4 balls on a 2nd shift league so normally I go with 3. One spare ball and two strike balls.
