The Solinco Hyper-G is a square shaped co-polyester string that offers an impressive combination of spin and precision. A Top50 ATP professional was involved in the development of the string, so it is not surprising that the string still offers phenomenal control even with hard hits and high playing pace and allows the player to pull the punch right through! Thanks to the first-class spin potential, players who like to play with topspin will get their money's worth here. Tension stability and playing comfort are above average compared to similar strings. With this very thin diameter, spin and playing characteristics are great!
