Wilson K6.1 95 18x20 to the Slazenger Pro Braided 95. My game improved significantly over a relatively short 5-6 month period.
My latest switch from the Slaz to the Tecnifibre TFight 325 has the potential to be an even better switch for my game...but it's still too early to tell.
USTA computer-rated 4.5
