What'd David Ferrer using under the paint? I know it's not the Control DB because it doesn't have the Air handle; I'm pretty sure that's it's not the Shark DB because he "changed" to that during the quarters of the French. My guess is that he's using the TT Warrior OS. Does anyone know? I'd particularly like to hear from thomas martinez, Richard Parnell, Michael Ludwig, or Grant Morgan. I'm also curious about his string setup. It looks to be Big Banger 16, probably in the high-50s. Who knows? Thanks in advance!
