Tracks R&D Department developed the 607ASE specifically positioned between the 505A and 715A, presenting a level of performance that bowlers are looking for, right between the two. The core is a modified version of the Legion core used in the Track Temper. Extreme Angularity is the strength of the âSE6â GEN1 coverstock, making this ball a dynamic choice for the oil patterns in typical house shots most competitive league bowlers face. Get it now, because there wont be another 6 for some time.
