Babolat RPM Blast 12m

One stringing's worth: 12 m of RPM Blast. Babolat labels this 100% co-polyester monofilament CONTROL, SPIN and DURABILITY, and it is a string for players who hit hard with spin: the firm string bed stops the ball from flying, and co-polyester takes a long time to break. It loses tension faster than a multifilament. Restring it regularly, even when the strings are still whole.
