Hello, I am looking for suggestions for a new racquet to suit my game because I do not want to go through the process again of play testing dozens of frames again. I am a 4.5 player who serves and volleys. When I am not serving I am always looking to chip and charge with my one handed backhand. I love doubles. I play tested dozens of frames last summer and at the time wasn't aware of racquet specs (HL vs. HH etc). As a result I chose I head heavy racquet the Wilson KFour which is good as the baseline and serves but is not maneuverable around the net. It also is too light (9.9 oz) and very stiff which has resulted in a mild case of tennis elbow for the first time ever. I am not strong enough at the preset time to use a very heavy racquet such as the K90 but I do need something in the 11 oz range. Anyone with similar game with suggestions? How are the new KBlades? Thanks!!
