It features the FSI Technology: More narrow stringing pattern around the “sweet spot” to bring more control to players with each strike of the ball Woofer system that allows for longer ball contact on the string bed for more control and comfort. Pre-strung with a cover.

The handle and the frame are linked by the C.D.S (Cortex Damping system) which filters and dampens vibrations interfering with feel. High frequency Vibrations which interfere with feel are filtered out whilst Low frequency which provide feel are maintained.

Woofer technology in the grommets is the first technology which makes the frame and the strings interact when striking the ball. This boils down to 25% more contact time between the ball and the strings which in turn means more control and a comfortable feel for you.
