Solinco Hyper-G is a square shaped co-poly with an impressive combination of spin and precision. Developed for an ATP top 50 player, this medium firm string will allow big hitters to take massive cuts at the ball without having to worry about over-hitting. Topspin players who like hitting balls that dive sharply and explode off the court should love this string. Try this version of Hyper-G for maximum spin and feel.
