Head YouTek IG Prestige MID Tennis Racket

The smallest but also heaviest (330g) version of the Prestige provides extra stability and swing to perfectly suit hard hitters, who are nonetheless looking for perfect touch and control.
What they say:
A legendary tour racket that offers maximum touch and precision. Added weight provides extra stability and is ideal for heavy hitters.
The Technology:
New YouTek IG Instinct rackets combines D30 and Innegra fibres for a frame that delivers power and control in a frame packed with feel.
D30 as used in other YouTek rackets is a smart material that stiffens up on hard impact shots (groundstrokes/serves) imparting power but remails flexible on soft impact shots (slice/drop shots) allowing greater control.
Innegra fibres which are extremely thin and tough are placed at strategic points to make the frame stiffer at those points making the frame more stable and less likely to cause twist.
