HEAD Radical: Though it retains the 16×19 string pattern from the previous model, the new MP is much more precise with a slightly denser string alignment. The variable 20/23/21 millimeter cross section is a little thicker than on the Radical Pro for a bit more power. HEAD bumped the weight up to 10.6 ounces (unstrung) with this version for a subtle improvement in stability. Graphene 360+ technology helps the Radical MP with improved stability in the head and shaft, while Spiralfibers at the 5 and 7 o’clock positions in the head provide plenty of flex for a soft feel at contact. HEAD’s new Sound Grommets give more power and string movement while maintaining a comfortable response throughout the racquet head. The Radical MP is a well rounded offering from HEAD that can suit many different abilities and game styles. The new MP also brings back a little of the iconic flex and comfort the Radical series was built on.
