Yu-na Kim!!
Her triple lutz has everything: height, distance, right edge, good flow in and out, and speed. I've seen it live at 2013 Worlds. Her 3lz+3t combo was huge, covering 1/3 of the rink!
Carolina's triple lutz is amazing, but IMO, she telegraphs too much.
Correct me if I'm wrong, but the long back outside-edge entrance for the lutz isn't really telegraphing, is it?
