Wilson adds a little more control with the new BLX Fierce. Even more impressive than the control is its amazing comfort. This comes in no small part from Wilson's time-tested BLX technology for ultimate racket dampening characteristics. This technology incorporates basalt fibers into the frame, limiting the vibrations that reach the arm and immensely improving feel for the ball. Whether you are an intermediate player searching for additional power and control or an older player looking to recover a lost step with a comfortable racket, the BLX Fierce is worth a serious look.
