The YouTek Radical MP provides the perfect combination of power and control. It features Head's YOUTEK technology that incorporates a new "smart material" into the frame called d3o. d3o is located in the shaft area where the racquet flexes the most and is able to sense the needs of the player during different strokes. On high impact strokes, the molecules lock together instantly to increase the stiffness of the racquet for more power. On slow speed strokes, the molecules absorb the impact to provide a softer touch for better feel. The Radical MP has a smaller head size and lighter weight than the Pro Model, but offers more control than the OS model. It's a maneuverable, powerful frame for players with long and fast swing styles. Recommended for 4.5-7.0 levels.
