so I weighted up the racquet to 10oz from 8 7/8 and this plays very well according to my son. He feels like he has more control and power is coming with less effort. He has used the racquet for over a week and no pain or discomfort. The only issue is that I can't get the putty to stick in the top of the racquet shaft. I shoved cotton all the way down the shaft, but I think it settled and now when the ball is hit there is a clunk clunk from the tungsten moving.
Anybody know a cure for this?
I was thinking of using glue to keep it in place but if I want to modify the racquet in the future that would not be an easy fix.
