I have tried the T500rs.. and will have one (F1) shipped to me pretty soon to review but in my opinion the fanatec will be better.. However i cannot prove it until I have reviewed both. (and its all about preferance) Also i hate static shifters so i wouldn't use that add on. I would use the paddles on the wheel
Is Thrustmaster sending you a comp unit to review? If so I feel bad for Thrustmaster. I can only assume they wasted money sending you a review unit of the T500RS with F1 wheel thinking it would be an unbiased review and here you are saying the Fanatec CSW will be better without even having one to try.
If you want anyone to take you seriously as a reviewer (if in fact they really sent you one), then you may want to consider reviewing the T500RS F1 Wheel on its own merits and not comparing it to an unreleased product that you've probably never even touched with your own hands.
