Havent used the CST's but would imagine them being remarkably similar to the Clubsports. I have used the G25/27(with and without a Loadcell), CSP+Tuning kit(currently Own) and have tried the new Thrustmaster and out of those its CSP all the way.
Is CST one of these? For what I voted, I selected the Fanatec CSP. Since it is the first pedals I have owned. None of friends own a wheel so I don't have anything to compare it to.
