RPM Blast Rough is a rougher version of RPM Blast for increased spin potential. The string offers a maximum spin thanks to its octagonal section, rough texture, and the Cross Linked Silicone, and unique sensation thanks to the High density Co-PET.
The SONIC PRO EDGE offers the same comfort and power level than its brother, the SONIC PRO, but has one tiny difference. It comes in a pentagonal shape, which allows ultimate spin. Made of special co-polymer material in combination with a soft molecular c
This monofilament string's inner crystalline core, which influences control, and the outer molecular chains, which influence power, are perfectly balanced thanks to the innovative Crystal Core Technology, a unique manufacturing process. Highly durable and
