I've never played with balls that are getting that big. It's as simple as that. I thought the balls in Rotterdam were quite heavy till I came here. You know, the court's definitely, you know, it's a little bit rough out there. That's always going to chop the balls up a little bit more than a smoother court, such as a US Open hard court. But, you know, there's no reason why the ball should get, you know, that heavy.
