Toroline O-Toro Tour Tennis String

Toroline O-Toro Tour Tennis String

Toroline O-Toro Tour is the highest-control, highest-stiffness variant in the O-Toro family — co-developed with former ATP Top-25 professional Steve Johnson for big hitters who want a tour-level co-poly that delivers tighter launch control, exceptional directional precision, and outstanding durability under the heavy swing speeds and high ball-contact volumes of serious competitive play. At approximately 15 percent stiffer than standard O-Toro, O-Toro Tour is not an everyday training string for casual players — it's a competition-grade co-poly built specifically for advanced players who generate their own pace, can drive through a firmer string bed without losing spin or penetration, and need a string that maintains its characteristics reliably through an entire competitive week.

Toroline's independent lab testing shows O-Toro Tour outspins both Luxilon 4G and Babolat RPM Blast while also testing more comfortable than either — a combination of spin production, control, and arm friendliness that positions it as a compelling upgrade over the standard tour poly options used by most competitive players. Each package includes two half sets (approximately 6.7 meters each) for one complete restring.

• Tour-Level Stiffness for Maximum Control - At ~15% stiffer than standard O-Toro, the Tour variant delivers a firmer, tighter string bed response that gives advanced players exceptional launch angle control, keeping balls penetrating and flat rather than ballooning — ideal for players who generate their own pace and want directional certainty over easy depth from the string.
• Hexagonal Profile for Consistent Spin - The six-sided shaped profile gives O-Toro Tour strong spin production despite its control-first stiffness character — the sharp edge geometry still bites and deflects through the ball on every groundstroke and serve, keeping spin generation reliable for players who use heavy topspin technique even within a firmer, more controlled string bed setup.
• Steve Johnson ATP Pro Collaboration - Co-developed through direct collaboration with touring professional Steve Johnson, who tested and refined O-Toro Tour's stiffness level, spin profile, and feel characteristics specifically to meet the demands of ATP-level match play — where control under full swing speed and durability through competitive use are non-negotiable requirements.
• Lab-Verified Spin Advantage Over 4G & RPM Blast - Independent lab testing confirms O-Toro Tour generates more topspin than Luxilon 4G and Babolat RPM Blast — two of the most widely used tour co-polys — while simultaneously testing more comfortable than both, giving players who currently use 4G or RPM Blast a legitimate upgrade option in every measurable performance category.
• Exceptional Tension Maintenance & Durability - The tour-grade co-poly construction resists tension loss and notching better than standard co-polys, maintaining its characteristic stiffness, control response, and spin profile across a longer lifespan — reducing the performance degradation that forces frequent restrings and delivering consistent feel from the first point through the final game of a competitive week.
• Built for High Swing Speed Players - O-Toro Tour's stiffer response requires the player to supply pace rather than relying on the string to contribute power — which makes it the right choice for advanced players with fast, aggressive swings, but not the right match for recreational players or those with slower racquet head speeds who need the string to provide more energy return at contact.
