Yonex Poly Tour Spin
Pentagonal co-polyester monofilament
Junior Player Guide
For ParentsRecommended Level
Tension for Juniors
48-52 lbs for juniors. Drop 3 lbs for more depth.
Gauge Recommendation
16L (1.25mm) for best spin.
Overview
Yonex Poly Tour Spin features a pentagonal shape for extra bite on every stroke. The most comfortable string in the Yonex Polytour range - soft on the arm while still providing spin and control. "If you're looking for control first and spin second, the Polytour Spin would be ideal." Shots leave the racquet with direct response and heavy spin, though may land shorter - drop tension 3 lbs for more loop and depth. Tension maintenance is excellent (12-16 hours) but some report dramatic drop-off when it dies. Good for defensive players setting up points with spin.
