I think there is already a thread on this but i couldn't find it so don't have a go at me if there is but i was wondering about his Pure Drive. I saw him playing today and it definitely looked like there was cortex in it, not just painted on. How heavy is it and what strings and tension does he use?? Yes he has switched to the cortex version!!!! Secondly on getty images there is a pic of him playing a backhand slice, and on the hoop of the racket there is a silver babolat sign and writing, is this lead??? Picture number is #74415054.
