I am 55, have been out of game for several years and now am returning. Had both knees replaced and so I will be playing doubles. Was 4.0-4.5 when I played and would say I am a 3.5-4.0 now. In the past i've had chronic tennis elbow. Even with the knees I like to serve and volley but not like I once did. Any suggestions on racquets for me? In addition, my wife is a 3.0-3.5 player and is looking for a new racquet. suggestions?
