RS Pro Edition Simon VasquezSimon Vasquez's model that he plays with is specially made with a longer grip and an Axis Force stabilizer for better range and reduced vibrations when hitting the ball. This is one of RS top models that has been manufactured with a drop / diamond shaped head and a hit surface of 12K aluminized carbon fiber that gives players with high swing speed the opportunity to create good speed in the over head game.The core is made of adaptive EVA material which gives the racket a larger sweet spot and minimizes the risk of reduced control in hits outside the center.There is also a 3D pattern on the face for extra spin and grip that can give a little extra effect in the slice but also good control for those who like to use slice in both the offensive and the defensive game.This racket is very suitable for experienced players who prioritize good speed in the over head game but still want control in the slower pace.
