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.
Polylon in short
Gosen Polylon is a good old-fashioned polyester string without extravagant chemical additives. What it does have is remarkable control, especially at the highest swing speeds, and tremendous spin potential. Its response is so predictable and low-powered that it enables big hitters to attack the ball at extreme upward angles. At only $2.95 per set, it's one of the all-time best options for big hitters on a budget. Extremely durable - one 16 gauge set survived about 35 hours of tennis.
