Head YOUTEK IG Extreme S 2.0 offers a plush feel and solid response from all areas of the court. This updated version includes S-Tech Grommets which expand the sweetspot and reduce the vibration. While the 9.9 ounce strung weight makes this the heaviest of the YOUTEK IG 2.0 Extremes, our testers did not find this one sluggish in play. The head light balance not only makes this racquet easy to position under pressure, it also helps players maximize head speed for added power and spin. Aggressive baseliners will have more than enough mass to hit heavy balls. At net, the combination of speed and stability makes this perfect for all-court players and doubles specialists. HEAD YouTek™ IG Extreme racquet is the weapon of choice for Azarenka, Youzhny, and Richard Gasquet. The HEAD YouTek Innegra technology significantly improves frame stability and increases the shock absorption. The new d3o technology reduces vibration and allows you to have a soft touch on feel shots but also stiffens the racquet when needing a little extra stability for hard hit balls. The racquet also uses a DuPont Teflon grommet system that reduces friction.
