Former Top 25 ATP Pro, Steve Johnson has been busy in the lab refining our best seller, O-TORO. Designed for the advanced level player, O-TORO TOUR has approximately a 15% increase in stiffness (comparable to Luxilon 4G and RPM Blast) resulting in more control, stability and durability. The increased stiffness enhances the string's responsiveness and stability at higher swing speeds. Also complements rackets with a softer flex (RA rating) or players that string at low tension.
