I've read in numerous places that pro's often play with older racquets and that the paintjobs change to match the current years offering. Federer, Nadal, Djoker, Murray, Ferrer - all guilty. The most frequent racquet quoted is the Head PT57 (Pro Tour 630) Thomas Musters old stick. Coupled with the large number of painted pro-stock PT57's that turn up for sale, it seems likely this is the actually the case. Question - what current pros use it. I've heard that Murray does and speculation that Djoker does to. Who else?
