Why a 6 series ball? Track’s R&D Department developed the 607ASE (Special Edition) specifically positioned between the 505A and 715A, presenting a level of performance that bowlers are looking for, right between the two.
The asymmetric core is a modified version of the "Legion" core used in the Track Temper. Extreme Angularity is the strength of the “SE6” GEN1 coverstock, making this ball a dynamic choice for the oil patterns in typical house shots most competitive league bowlers face. Cover of the 607A is Black/Red?Yellow and finished 500, 1000, 2000, 4000 then polished with Powerhouse Factory Finish. 15# RG is 2.46, and RG Differential is .041. Available 8/5/10.
