Wilson Shift 99/315 Pro
The Wilson Shift has introduced a new movement in racquet design, and the Shift 99/315 Pro rounds out the two (2) racquet series for now!
If you read the review of the 99/300 Shift, you have a good idea about the concept: on the impact, the ball moves the head down, and before the ball can leave the strings, the head moves up!
It is like you are swinging from low to high! It sounds simple, but there is more to it than that.
