The Head YouTek Radical MP is a premier tennis racquet recommended for professional players at the 4.0+ level—but can also be used by intermediate to advanced juniors/adults as well. More specifically, it’s built for handling both topspin rippers and slice/dice players. Its primary component is Head’s new YouTek technology, which includes d3o adaptive materials that change behavior under dynamic loading or impact; Teflon for less friction and greater power; and Aramid bumpers. The d30 materials — dubbed ‘smart materials’ — host meta-morphing molecules that remain soft during slow hits, but lock up tight on harder, more powerful strokes. It essentially ‘senses your needs’ and then adapts accordingly. Notable professionals who use the YouTek Radical MP include Marin Cilic, Amelie Mauresmo, and Patty Schnyder.
