I've been thinking of getting a new racket for a while, as although I've had re-string, new grip....it just doesn't feel like it's good enough any more.I've been playing with an old Carlton Airblade 2000, with BG60 strung at 23lbs. I'm playing in a local club, which is predominantly doubles. But I also play singles regularly. My game is based around moving my opponent around the court and love SMASHING!!I've got a couple of options on rackets, but don't really know if there's much difference between them....Carlton Vapour Trail TourLi-ning Flame N36I'm used to Carltons, so switching to Li-ning would be a leap of faith....so, I'm really hoping for some advice....as unfortunately I can't try either racket before I buy....So....please HELP!!
