Here at Tennisplanet we feature several HEAD rackets within the HEAD Extreme series, with each model featuring unique specifications to help improve your game. The HEAD Graphene XT Extreme Pro is the heaviest racket in the HEAD Extreme series, which allows more power to be placed into the shot with. The HEAD Graphene XT Extreme Lite, on the other hand, is the lightest in this series which is ideal for when you are looking for a slightly more agile racket. The HEAD Graphene XT Extreme MP A is also perfectly suited to provide spin to the ball in addition to power.
