I thought that he uses Tecnifibre racquets? What are these blue ones that he was destroying earlier today? Looks nothing like what Technifibre has to offer unless they've been given a custom paint job. Is it a prototype racquet? Has he switched to a new company? Here's a video of him destroying a few of them earlier today at the Australian Open. http://www.youtube.com/watch?feature=player_embedded&v=mM02295xo88 I'm sure that some of you would know. Thank you.
