Signum Pro Poly Plasma 17L/1.18 Reel - 660'

Poly Plasma offers exceptional control and is very spin friendly. This one is a great choice for aggressive players seeking a durable string that offers enough control to allow for high swing speeds. Its co-polyester construction makes it more comfortable and better at holding tension compared to traditional polyester offerings. We found this one to be noticeably softer than many co-polyester strings.
