She is looking really good! I hope she's playing well and all that. It's good that she has this kind of 'i'm still in the middle of my season' mindset so she can keep her momentum from Quebec City going through to this year.
That racquet looks like a K-Tour, but it's most likely a paintjob. I know she said she was going to experiment with the new technology over the off season and possibly make a switch, I always thought that was unlikely, given she's in the last stages of her career.
On a side note, I'm not loving the hair - she needs to grow it again
