btw, the check out the videos of the masters on http://tennistv.nl/
There is a Kiki clip where she is playing with her new racquet. Still the Wilson Blade, but the new one. Don't like it actually, but whatever.
She does have yellow string
Aran is also playing with a new racquet, you can see her in the clip too. It looks like the Wilson Steam but it's seems to be a bit different.
