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.
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
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
