Poly produces spin!I’ve always been told that polyester strings create more spin than nylon.  Now there is proof with complicated physics to show that is a fact.  According to an article from Tennis Warehouse University (where the physics got interesting really quickly), it seems to prove what we’ve always heard anyway and why I play with a poly/nylon hybrid string patter. 🙂

“Experiments were conducted to compare the spin generated by 16 different tennis strings, using both clamped and hand-held racquets.  The results obtained in this paper support those previously obtained by the ITF, and commonly reported by players themselves, indicating that polyester strings generate more spin than nylon strings.” – Tennis Warehouse University
