Hi. I currently use a Babolat Pure Drive but i havent played tennis for a few weeks becuase it is winter and i have no indoor courts near me. (I live in the UK). Since using the Pure Drive for about a year i have experienced some problems with my shoulder quite recently and i put it down to the racket because of everything i have read and other peoples problems. I am looking to change my racket and hope to go to Wilson as i like the lightness of their rackets - i am male but not that strong and still growing and i need something to help me improve my game. I find 310 grams plus is too heavy and just not manouverable enough. I really like the look of the Wilson N4 (Venus blue one) but not the oversized version. Will this racket be better for my arm than the Pure Drive? Also would it be better for my arm than the Pure Storm MP (yellow one) which i have also recently purchased but played with once. I would add lead tape to the grip to balance the racket out but my question is simple - which is better for my arm? I would just like an answer then you can suggest other rackets from Wilson which may be better as i'm sure you will. Please reply so i can get out of this rut i am in and can start preparing for the Summer - thanks.
