The Yonex VCORE PRO 97H offers best in class stability thanks to the 11.6 ounce unstrung weight. Yonex added Flex Fuse technology with this update, which integrates a shock-absorbing polymer within the graphite’s resin for improved racquet flex and a softer feel. The new technology results in a thicker 21 millimeter cross section which produces more stability. To further establish the VCORE PRO as a control racquet, Yonex redesigned the shaft with the FlexCon System; a tapered and elongated box-frame design for greater precision. Like the previous version, Vibration Dampening Mesh is wrapped around the graphite handle (beneath the grip) to filter out unwanted vibrations. Yonex' Flex Force graphite means the racquet can flex, but it snaps back quickly for greater spin and ball acceleration.
