Forten Sweet 16 tennis string uses a specially formulated bonding agent in the development of this synthetic gut. Sweet efficiently returns energy to the ball during serve and volley play for livelier response without tension loss. Its tensile strength allows it to take the pounding of a baseline rally. A Polyamid Composite offers a softer, more natural “feel” than the strings made from more durable materials such as polyester and Aramid fiber strings. They play well and are both durable and cost effective. Manufacturing processes have enhanced nylon strings’ performance so that the strings emulate the highly desirable characteristics of natural gut without the high cost.
