RS PARIS Octagon string was developed by Robin Söderling. This is a string that Robin has spent a long time developing to perfect the balance between spin and power. RS PARIS is stiffer than RS LYON, but still decent in terms of stiffness for being a polystring. The octagon profile makes the spin effect sensational. You will have a nice and crisp feel in your shots and a superior durability of the tension, just like the RS LYON. Have you played Tour Bite or RPM Blast? Then you will just love this one.
