When it comes to skating skills(deep edges, versatile turns with speed) and jumps technique-wise(scale, coverage, height, distance, etc), Carolina is way ahead of the rest of ladies who will possibly show up at this coming worlds. Maybe she is yet to include difficult lutz and flip willingly in her programs but if she does which I'm sure she will by March, Carolina would be the most contending lady. Mao's 2a-3t at NHK was very impressive given what she had shown for the last couple of seasons, but her flutz was still there, and her flips which used to amaze me with the huge scale has not come back yet. It's still a working process and giving out some positive results finally. But Mao's still got lots of things to prove further to be the most desirable candidate for the world champion IMO. If she does all those things right and tremendously improves her technique, Mao is gonna be the one to beat and when she's on the top of the podium this season, it'll be her third title and that's what no one else has done since Michelle Kwan. That's kinda awesome but will she be able to deliver that?
