The latest update to the slightly heavier and 0.5 inch longer Babolat Pure Drive Roddick Plus, the new Pure Drive Roddick GT (Graphite Tungsten) Plus 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 Pure 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. Only those frequencies that enhance feel are permitted to pass through the Cortex filter.
