I highly recommend that everybody watch her exhibition at the recent US nationals. Karen skates to traditional Chinese music with two ginormous feathered fans, and she does her spins, her jumps (among them a perfect 3lutz) footwork and spirals while manipulating her props! She has all her triples (except the flip that she lips), a 2axel/3toe combo she's done regularly in competition and very solid basics. She's very, very promising.
And I didn't know how thoughtful and well-spoken she is before reading this interview. It's amazing that she's not even old enough to compete on the Junior Grand Prix!
