With the Rising S.E. (Special Edition) Track has engineered a ball (for lack of a better word) with the strongest core to date, a single density monster with a cranked up intermediate differential of 0.035, an all-new high. Then Track wrapped it all in a GEN 2 coverstock with a performance pearl additive to increase length while storing energy. It’s the closest thing to a remote controlled ball for the slickest lane conditions.
