I'm an all court player. I have a big serve which is a weapon with the right stringbed but I like a compromise between firmness for serve and softness for touch shots. I have played with Biphase 16 @ 55 (lasted 8 hours before snapped) and thought it was amazing and I will always have a racket strung up with this (I actually had great spin but loved the ability to hit flat winners consistently). Just felt the need to see what the gut/poly hybrid was all about. I would say my main priorities are good power and spin (i find my racket provides great control), cost isn't too much of an issue as this could be a tournament setup in my mind.
