The Babolat AeroPro Drive GT (Graphite Tungsten) Plus is the longer length update to one of the most versatile racquets on the market today. GT technology adds a hybrid of braided carbon fibers and tungsten filaments throughout the entire racquet. Tungsten strengthens the frame to reduce torque for greater precision (Babolat claims 26% more precision compared to the previous Aeropro Drive). Babolat continues to utilize the Cortex vibration filter at the top of the handle. Cortex is used in several of Babolat's players racquets to enhance feel by cancelling only the 2 highest vibration frequencies
