The Luxilon 4G 125 Limited Edition Tennis String Black is the perfect compliment for the Wilson Night Session Racquet series. This string still carries excellent durability, but with above average feel and comfort compared to most mono-filament strings. For the advanced players that break strings but are looking for something a little softer that will hold tension better, this string offers great control and accounts for less shock than the other, harsher poly strings. This string still has the power and spin that you would expect a Luxilon string to have, but with the new enhanced feel.
