Federer uses the ksixone so that may be good for you. I find the babolat pure drive gt plus offers more power and control with a smooth swing. I have a good power forehand with it with good consistency Using a smooth swing. I like prince synthetic gut 16 strigs on t strung at 59, but lexilon and babolat pro hurricane strngs are also good. A hybrid with pro hurricane and vs strings feels good too. String at your prefence. Anyway, look into the pure drive series or a ksixone.
