Best suited to 4.0+ rated players who want exceptional maneuverability and control from all areas of the court, the VCore Xi 98 updates the V Core 98 D with some extra comfort, stability and power. Yonex's Xi Technology (Extra Isometric Head Shape) expands the sweetspot toward the top of the frame, while the Micro Core technology strengthens and adds weight to the upper hoop. Taken together, these updates not only deliver a more arm-friendly ride, they give advanced players a more responsive contact zone higher in the stringbed. From the baseline the feel is one of crisp comfort and spin-friendly precision, while at net the blend of maneuverability and stability make for easy volleying. The manageable swingweight (311 RDC) and headlight balance help propel the racquet swiftly through contact on serves. The result is easy access to spin and power from the first serve to the finishing shot.
