Specializing in spin and power, the Babolat Pure Aero is one of the game's most legendary racquets. At 11.2 ounces strung, this stick is ideal for hard charging intermediate players, but it should also work very well for the advanced ball striker who is looking to go on offense. For this update, Babolat lowers the flex a tad, giving this notoriously stiff stick a slightly more controlled and arm-friendly response. Babolat has also moved the Cortex dampening material to the head at 3 & 9 o'clock, resulting in a slightly softer feel at impact. But make no mistake: this is still a firm, modern and lively weapon. The signature technology, called FSI Spin, utilizes wider string spacing for extra bite along with oblong grommets at 6 and 12 o'clock to maximize string movement and snapback. Like the player who endorses this racquet (Rafael Nadal), the Pure Aero feels fast and explosive from the baseline.
