Carbon Tech Two layers of high-performance carbon are integrated into the blade improving rigidity and response, which results in increased speed and power. Nano Composite Technology Stronger and tighter bonds in the rubber increase speed and spin. ACS Numerous microscopic air-capsules in an ultralight rubber allows high speed to be combined with maximum elasticity and outstanding control. WRB Weight Balance: The balance of the blade is shifted to the point of contact with the ball. Rate of Recovery: The decrease in blade weight improves rate of recovery after each stroke. Ball Sensitivity: The strategically positioned recess in the handle provides extra sensitivity of touch.
