she can forget justine because other than clay, Justine isn't a player to really be too afraid of and you don't often see her as the top contender at a big tournament other than ones on clay. sure, she can have good results on slower hard courts, but she it comes down to it, those players that she mentioned are very dangerous on any surface (even Lindsay is a bit on clay even though she hates the surface). Justine hasn't played well at the USO since she won and she lost in the first round of Wimbeldon last year. Justine is great on clay and a slower hard court, but I would favor other players on faster surfaces. That's no knock to Justine, but I never put her as a favorite at a tournament unless it is on clay or a slower hard court like in Dubai/Indian Wells or Rebound Ace. She can be overpowered on fast courts more easily than the others.
btw, I don't think that Flavia meant to leave Justine out, but if she meant it, I'm defending that.
