I think the Track 10 is correct, but my interest in Track balls began shortly after with their Enforcer series--I bought all three--The Blue, Burgundy, and Black Enforcers. All good equipment, as good or better than other urethane equipment of that era. They came out with the Polyester Enforcer, a crimson Red spare/dry lane ball that was a winner--I once shot 234, 278, 278 with one, causing a buddy of mine to go and buy one the next day! He never got that good a series with it, but he did soot a 300 with it about a year later. I wish the would remake that ball...
