I am a female player in the 50’s. I had been playing for several years at 3.0 level. My tennis game has been improved noticeably since last year and I am playing at 3.5 level now. I would like to upgrade my racquet from Prince O3 Silver to something that has more control. I also have mild tennis elbow from time to time. So I also would like to have a racquet that is arm friendly. I have restrung O3 Silver with multifilament string (NXT) 3 month ago and it helps for my tennis elbow. So I probably will stay with this type of string. Basically I am not looking for any radically different racquet than my current Prince O3 Silver. I just want a step up in more control and less stiff racquet. I am looking at the following two possible replacements: 1. Prince O3 Blue Blue is basically the same racquet as Sliver with smaller head (110 in2 vs. 118 in2) and less stiff (66 frame stiffness vs. 74). I assume that smaller head will have more control. Blue is 0.5 oz (10.1 vs. 9.6) heavier than Silver. Its power level is also little lower. 2. Prince EXO3 Tour Team 100 I saw a lot of positive reviews about EXO3 Tour racquets. My understanding is that EXO3 tour is a newer series of racquet than the O3 series although I don’t know what the major advantage is for the EXO3 series. The head size for Tour is much smaller (100 in2 vs. 118 in2). I don’t know if this would be too much change for me. The power level for the Tour is also much lower (low-medium vs. high). I don’t have much power myself and would like to have a racquet that has decent power level. Tour is also much heavier than Silver (10.6 oz vs. 9.6 oz). Based on your experience which racquet will suit my needs better and/or if you have any other better racquet to suggest. Your help would be greatly appreciated.
