Ellipse Explosion

As the graphics would suggest this racquet was designed for the aggressive Junior player!  Not only was the graphic aggressive the specifications were meant to give the player huge stability, which corresponds to power and control.

The makeup of this racquet was the same as all the Ellipse Sport models but the weight and swing weight were “tweaked” to make the racquet do most of the work for the player, assuming the player could get it moving!  The specs below will confirm the idea.

The “Matrix” string system used on all Ellipse Sport racquets created a very consistent bounce off the string bed.  The open pattern created a lot of spin potential.
