I am looking for recommendations for a racquet that will help my son with his off & on shoulder tendonitis. He is a 5.0 all-court college player that has always used a Prince Precision 770 racquet since he began playing 10 years ago. Based upon info here we are looking at demoing the Prince 03 tour, the Wilson n-code 6.1 95 and possibly the Wilson n-tour 95. What do you think? Thanks for your help.
