If you remember the trophy ceremony at Miami, there was a brief exchange between Mary Joe Fernandez and Kolya Davydenko about his new stick. It sounded like he only had one in his bag, but a rep from Prince said otherwise. Not only did he have enough of the Ozone Pro Tour (which he just switched to), but he also had access to the Ozone Tour racquets he’d been playing with prior to Miami.
And re: his shoes, aparentemente he was very particular about picking a new pair. He tried on shoes from Nike, adidas, etc. — and he had even tried on a different brand for the first round before settling into the Prince O-Series. And he lived happily ever after.
