The V Core Si 105 is a perfect for beginner and intermediate level players looking for a light, lively and comfortable racquet. The 105in² head size provides a generous sweetspot without feeling overly powerful or unpredictable. The light weight makes it easy to swing this stick fast when adding pace and spin. To further enhance spin potential, Yonex adds its BT Hybrid Grommet System, a feature that allows the strings to move out of position and then snap back with greater force. From the baseline, the Si 105 feels comfortably solid at impact. Aggressive baseliners will find the needed blend of power and precision to hit penetrating groundstrokes. At net this racquet provides a generous hitting area for making clean contact and blocking the ball back with depth. There's also plenty of power and spin to be had on serves where this one whips very easily through contact. A nice option for the player who wants a comfortable racquet that supplies easy access to power along with more than enough control to attack the ball with confidence.

*This racquet is compatible with the Sony Smart Tennis Sensor.
