I have been out of tennis for the last 5 years after playing intensely for over 20.I recently tried the Wilson K Blade tour 93,Six-One 95 18 x 20 and the Babolat Aeropro Drive.I loved the control that I experienced with the Wilsons however my shoulder was very sore(something I did not experience with the Babolat).I am wondering if these particular Wilson models are too heavy although there is not a significant difference in weight between the three racquets.I am going to demo the K blade tour 98, the K factor six one team,K pro tour 96" tour and the K factor K pro open 100".I would appreciate any helpful advice.What are your thoughts about the above mentioned Wisons and the Aeropro Drive?Thanks in advance.
