This was Jim Courier's racquet of choice (originally in black, and most recently in orange). For players who want supreme maneuverability in a power-packed frame of substantial stationary weight. The X-P Dual's 11 ounce heft is offset by an extreme head-light face, providing more plow-through on ground strokes and racquet-head speed on serves. Dual XeneCores provide tremendous stability and control not otherwise found in a larger head size. For players who want the power and forgiveness of a larger frame, but the speed and stability of a mid-size. These were purchased directly from Donnay during its transition over to Xenecore, and production of this version of the racquet was limited. They are both in excellent condition (9/10) with some minimal wear on the scratch guards. Both are strung with Tecnifibre X-One Bi-Phase strung at 50lbs. and both string sets have quite a bit of life left. I am selling these racquets as a pair. Both racquets have new Wilson grips and Gamma Shockbuster II dampeners. They can also be customized with Donnay's weight kits which can be purchased directly from Donnay/Xenecore's website.
