TOROLINE's most anticipated release ever. O-TORO was co-developed with former Top 25 ATP Pro, Steve Johnson. Racketpedia lab tested O-TORO 100 out of 100 for spin and more comfortable than many of the top selling co-polys on the market. Compared to Luxilon Alu Power, O-TORO lab tested higher for spin, control, playing life, and comfort. Look no further for the best value co-poly string on the market!
