Track Criterion Inverse Bowling Balls Weights:13 lbs Powered by the Surge™ CoreThe Criterion Inverse literally turns convention on its head. By switching the densities of the two density inner core that were already proven in earlier Criterion releases, Track has created new core numbers and a whole new motion on the lanes. The result is a cleaner, more controlled reaction that smoothly blends wet and dry transitions. This is better than traditional asymmetric balls, which tend to read too early or jump too hard off the spot.
