I had bought a Metallix 2 racquet and switched to it, but I came back to this. I found the Metallix 2 racquet was unstable in the upper part of the frame, and it was way too light. This is an improvement in the weight. It has lots of spin and a perfect blend of power and control. It feels pretty solid, especially at the net. The sweetspot is huge. It is also easy on the arm. Although I don't like the Forten synthetic gut strung in it, though. I would recommend this racquet to anyone." - Courtney, BC, Canada
