I am 40 years old and have been playing for 15 years. I'd say I'm at a 3.5 level though I have made it to 4.0 a couple of years ago. the last couple of years i have become injury prone. Wrist problem, tennis elbow and now shoulder injury. Although those are only minor injuries, i want to use the best forgiving racquet for my type of game. I want to replace my wilson 3.6 with rollers which is a head heavy power racquet (stiffness 74, weight 9.3). I am comfortable with this racquet. I have a medium swing, all around game. I really need an advice on which racquets should i consider buying. Thanks.
