Hi Guys. My friends was wondering if I am able to string his prince graphite. Unforunately I came upon a dilemma. Here is the picture of the grommets on the outside of the racket: 1.http://tinypic.com/r/2zfpf7p/3 2. http://tinypic.com/r/30jjonc/3 The grommets seem to be detached from each other. He says the racket is pretty old. The whole racket is pretty much like that except for the throat where the grommets seem to be proper. Is this safe to string?
