930T Product Notes

Manufacturer's Intent

This first ball in the all-new 9 Series, the 930T, was designed to be extremely aggressive at the breakpoint.  The 930T has “Mica” embedded into the coverstock, which gives this ball extra TRACKtion at the breakpoint so you can expect a heavy roll in the backend.  Each new ball from Track will now include a microfiber cleaning pouch with instructions on its use. We feel this will be a great addition to help our customers maintain their performance products.
