I have been playing for 1 year and since January I am playing with a K 6.1 95 (18 x 20). I tried a more user and beginner friendly rackets but did not have the same feel with the K 6.1 95 (18 x 20). The racket was strung with Wilson Sensation probably a bit lower mid tension which must be 53-54 lbs. Since March I got it strung with Babolat Tonic (16) at 57,7 lbs(=26kg). After all that time for a reason I feel that with the Babolat Tonic even strung at nearly 58 lbs the control is less than with the Wilson Sensation string that came with... Since I am not playing much time I did not want to try any poly string because I want to stay away from any possible TE and that was one of the reasons I tried the natural gut. I never had TE. Have you any particular string set up or kind to suggest for a K 6.1 95 ( 18 x 20). I play mostly from the baseline and like to finish points early with winners.
