Yonex RQS 33

Power Isometric: 20% larger effective Isometric area in the heart of the frame allows serves to be delivered with more speed and control from higher in the stringbed.
Nanoscale Elastic Ti: Racquets featuring "Elastic Ti" will snap-back quicker than conventional racquets to give higher repulsion power with accurate resiliency for improved face stability. These two effects mean that greater ball speed and control are realised. 
Dual 3D Stabilizer: The Yonex "3D Carbon Sheet" integrated into the shaft provides more face stability than a conventional carbon shaft and 12% more racquet manoeuvrability.
OPS: Oval Pressed Shaft technology builds into the throat, giving the right amount of flex for an extended dwell time for easier spin and directional control.
IPS: Integrated Power Weight System positions extra weight at 3 and 9 o'clock on the frame, giving the face of the frame a greater moment of inertia. The "IPS" construction translates into minimum torque within the frame for maximum stability, energy transfer and control. 
Nano Silver Grip: The Yonex Nano-scale silver compound, an integral component of the grip construction provides a combination of a high level of comfort and built-in antibacterial performance for the hand.
