the problem is my fathers racquet, is a wilson titanium stretch (28''). i tried it a few days ago and i coulndt believe how much this racquet vibrates, i can feel how my arm vibrates because of it, is a awful feeling. and sice my father is older and he doesnt generate as much raquet speed as i do, i think its even worse for him. the racquet has a shock dampener (head smartsorb), and is strung with psgd16 at 57.what can i do to make the racquet vibrate less? i was thinking maybe stringing it with a soft multi.
