This racquet has some similarities to the Head Graphene Speed Pro, which is the racquet that Novak Djokovic has played with ever since Head integrated the Graphene technology into their racquet lineup. At the time of this review, you seem to be getting a great deal on this racquet, as the price is equal to the Djokovic racquet, but without the Djokovic price tag. The extreme pro is a new racquet in the lineup and includes S-Tech grommets, which helps the stringbed to absorb much of the shock at impact. Of course you still get to enjoy the Graphene technology that provides a perfect balance of weight in the tip and handle of the racquet.
The thicker beam is what really sets this racquet apart from the Speed Pro racquet. Players get a much better response, but without giving up too much control aided by the stiffness of frame at 69. Obviously this is not the racquet for players with arm and shoulder problems, but on the other hand not so stiff as to make it uncomfortable to play with in longer matches either.
The Graphene racquets are popular among the ATP and WTA players, and Richard Gasguet and Mikhail Youzhny are both playing with the Head Graphene Extreme Pro.
