This Yonex V Core Pro 97 HG 330 - Matte Green is one of the most popular frames on the pro tour. The stretchy mesh material bonds well with the graphite under the grip to minimize vibrations by 30%. The Lock Booster system is an improved grommet design that promotes string contact for better energy transfer and spin generation. At contact, the strings "lock" against the ball for aggressive, attacking spin. The head-light balance is fast through the hitting zone, and the thin 20 mm beam adds a high level of mobility. This racquet comes with a cover.
