G-Tour 3 in short
Gosen G-Tour 3 is a co-poly made from a high-purity polymer with a silicone oil coating for snapback and longevity. Tennis Warehouse calls it one of the more comfortable co-polys on the market, slightly softer than G-Tour 1 while still giving excellent control. The low-powered response lets players swing hard for pace and spin, and reviewers praise its comfort, spin and durability.
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.
