Track’s 505T is a ball that clears the heads well, is very strong in the mid-lane, and continues through the body of the pattern. The 505T is constructed with the proven shuttle core, its final appearance in the Track line. The shuttle core was then wrapped with a brand new coverstock blend, the MP GEN 4 – creating the strongest coverstock Track has ever used in a mid priced ball.
