One of Gamma's best control strings gets softer!  Gamma iO Soft 15L/1.40 String Reel is a more forgiving version of iO poly, that offers less shock on impact than stiffer co-polyester strings. The softer feel provides generous power and greater feel without harsh vibrations. Ideal for intermediate to advanced players.   This is a great option for the player who wants the freedom to attack the ball without having to worry about over-hitting.
