Head updates the Instinct PWR with some extra stability and power. This version is called the Graphene 360 Instinct PWR and it is perfect for beginner and intermediate players. It should also work for the savvy doubles specialist who wants a a little extra pop on serve. Like its predecessor, this racquet's extended 27.7" length will enable you to attack the ball with extra momentum (think big power). Like other members of the Instinct family, this racquet gets updated with Graphene 360, a technology that gives you the benefits of polarized weighting while also strengthening multiple locations around the head for a more stable and powerful response. Compared to the previous generation, this update swings a tad heavier. The result is a more solid and arm-friendly feel at impact. There's also more power under the hood, making it easier for less advanced players to take control of the point. Comfort and power are further enhanced by this racquet's large 115in² head, which feels wonderfully forgiving on off-center hits. From the baseline this stick not only feels solid against higher levels of pace, but it rewards shorter strokes with effective depth. Players who swing this racquet fast will find blistering power, and the large head size provides a nice margin of error, ensuring that performance remains high when contact is less than perfect. At net the Instinct PWR feels stable on block volleys, and the generous headsize makes it easy to achieve clean and effective contact with the ball. Finally, the extended length will supercharge your serve, making this a great weapon for forcing weak replies. Players looking to get more from their compact strokes should love this one as much as the doubles specialist looking to turn up the heat.
