Here we can see her old racquet, the Drive Z Tour. The Cortex looks legit. I'll dig up specs in a second.
EDIT: The Drive Z Tour is 10.1 unstrung and six points headlight (also unstrung). It's 100 square inches and has a 23-25mm beam. Comparing this to the Pure Drive Lite, the racquets have exactly the same specs, except the PDL has a 22-25-22mm beam.
