I have been stringing for a while now, and recently restrung two rackets (one cause it broke, and the other becuase I was feeling rather giddy that day ). Anyways, this problem has always been lingering at the back of my head, and I must ask it. Is it normal for the racket head to shrink after stringing? The shrinkage is about one wide of the frame, so when I put it to an unstrung frame, you can see that the unstrung frame is about halfe the width of a frame longer (about 4 mm). Width wise, about one quater or less of a frame (2mm maybe?). The shrinkage is very proportional to the iso-shape of the racket head, so it looks perfectly normal. The shrinkage is not significant, and the frmae pops back after the strings are removed, but still, does this happen to you guys?
