The choice of Stan Wawrinka (SWI) ! The VCORE Pro 97 (310g) sports a relatively compact 97in² head and flexibile 21mm beam, giving it great control and outstanding feedback at ball impact. At 310g (unstrung), this extremely stable racquet is suitable for intermediate to comptetition players. For this generation of the VCORE PRO franchise, Yonex implements an Improved Throat Design, which combines a thinner and longer shaft with a lowered throat, resulting in more torque, dwell time and spin-potential. Also new to this series is a Vibration Dampening Mesh (VDM), which is integrated into the handle in order to reduce unwanted vibrations for a cleaner feel. The Namd,is still used to optimize the response. The signature technology remains the Isometric head shape, which is designed to feel roomier than conventionally shaped equivalents. This racquet also features a Lock Booster System, which features raised ridges in the grommet strip for enhanced power. From the baseline, the VCORE Pro 97 feels crisp and accurate, and the updated 16x19 string pattern gives it plenty of spin. This racquet feels quite handy at the net and on touch shots. Like its predecessor, it will give aggressive servers the needed precision to swing for power, and there is more than enough spin potential to work the ball into tight spaces. All in all, the VCORE Pro 97 (310) remains a very solid option for confirmed players looking for stability and control. Played on tour by Stan "the man" Wawrinka (SWI) in the 330g version.
