i love this racket except that i have a string problem. polyester is terrible on this racket. i dont know why but it just does. after using poly on this, i switched to gamma professional 16g strung at 60 pounds and i fell in love with it EXCEPT that i break the strings every 1-2 days. my friend recommended wilson sensation on the k98. anyone else have the same problem and know strings that can match the racket?
