I had played with RDX 500 90 today, the Muscle power grommet of the MP1-Tour is no longer existed. the racket is in hexacon cross section instead of triangle and it is composed of tungsten, ni-ti, NM graphite and graphite. the feels compare with Super RD 90 or MP1-Tour is more stiffer and the control is wonderful. If you want to take a closer look at that racket, please drop a email to me.
