The racket was damaged when I was playing a stick smash in a double game from the mid-court. There were no collusion during the play and the racket was strung at 24 lbs with Yonex BG 66. My friend who owns a badminton pro shop help me replace the handle of the racket. But it doesn't feel as good as before. There is slight vibration in the racket now. Sigh.
