The headsize at 99 square inches provides a blend of control and power with a forgiving feel. This model comes equipped with a denser string pattern to enhance its control potential. The heavier than average weight at 11.1 ounces (unstrung) will provide exceptional stability and power generation on big swings for players who can swing a heavier racquet over the course of a match. Its head-light balance (unstrung) increases your ability to move the frame quickly, an important factor in generating power as well as being conducive to fast movements at the net for game-changing volleys. Built around the insight of maximum lateral bending and best in class torsional stability, Shift allows players to hit the ball consistently deep in the court with increased confidence and spin on each shot.
