The string package comes with 1/2 set of T1-Firewire (Rated #1 in Spin for three years) and 1/2 set of Ghost Wire;  a round co-polyester string tested as one of the softest strings in its category (lab tests by the United States Racquet Stringers Association). The combination of those two strings creates a setup that has rarely been challenged in the spin category. In addition, Ghost Wire will offer additional control, arm-friendliness, and feel to this unique setup.
