The Wilson Profile series is recognized as the successful introduction of very stiff racquets to the mass market. The Profile, while not for everyone, suited a various style of player. The 110 square inch size simply allowed the player to make contact with the ball anywhere on the string bed and it had a really good chance of being a good shot. The 95 square inch we are looking at here did require slightly more “talent” to maximize the racquet’s performance.

What made the Profile so unique? Perhaps it was the patented “vibration frequency” which dictated the shape, or Profile, of the series. Vibration frequency is the best way to test for racquet stiffness and stiffness is a huge contributor to “power”. I don’t remember the specifications exactly but the frequency ranged from 200 to 225 Hz. So, no other racquet manufacturer could produce a racquet that fell into that frequency range.
