Poly Tour Pro in short
Yonex Poly Tour Pro is a softer playing poly stretched at high temperature during production to improve tension maintenance. "I felt like I could put the ball on a dime with it!" - exceptional control on fast swings. The ball seems to sink into it like a pillow at contact. Despite being firm, it has above average comfort for a poly with the yellow version playing slightly softer than black. Not the most spin-friendly in the Yonex family (actually the least), but the control and predictable response make it a favorite among power players. Don't try to get more than a month out of it - when it dies, it's done.
Poly Tour Spin in short
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.
