Of the modern racquets in the past five years, the Prince EXO3 Tour has become the standard of a “player’s racquet” (level 3.5 or above) that is very easy on the arm. The flex rating of this Prince is an astounding 52 stiffness which means the EXO3 Tour is extremely flexible. Thanks to the thermoplastic resin reducing string vibration and amping up the comfort level, the Tour model absorbs much of the shock and vibration from shots even if they are mishit. While this technology does create a flexible feel that takes getting used to, it does not take away from the professional level of the racquet. The EXO3 technology gives huge access to spin and the middle tier strung weight of 11.6 ounces / 328.85 grams creates fast racquet head speed to generate power. The lighter weight of the racquet also gives great control at the net and volleys are a pleasure. This is a control racquet and some may find power a tad less compared to very stiff racquets like the Babolat Pure Drive but the trade off is well worth the arm friendliness and additional control.
