A spin-friendly option for the advanced level player, this 97 square- inch offering from Yonex blends plow through mass with maneuverability. Yonex has kept the weight just over 12 ounces strung to meet the stability needs of advanced players, yet has a head light balance to maximize swing speed for the ultimate spin. Yonex's traditional Isometric headisze provides an expanded sweetspot for forgiving power and increased comfort throughout the stringbed. The flexible frame increases the player's sense of dwell time (when the ball is on the strings) providing added feel to touch shots and more spin capability. All in all, this is a great option for the 4.0+ level player looking to add spin, feel, control and maneuverability without sacrificing stability.
