The oval-shaped pressed shaft is designed to provide players with more spin, control and feel. The shaft flexes on impact, increasing dwell time and minimizing vibration.Vibration Dampening Mesh (VDM) – First used in Yonex snowboards to reduce vibration on impact, Vibration Dampening Mesh (VDM) is now used in four series of racquets. VDM is a stretchable mesh material wrapped around the graphite in the grip to dampen unwanted vibrations and improve feel and precision.
