Yu-Na better than Mao in jump?? Never true.
First, Mao has great triple flip and combination while Yu-Na does cheating jump on flip, you can know this because she gets wrong edges and ! marks for years. Mao is not doing triple flip combination this season because she can do more superior 3A even in short and two of them in long. The reason that she isn't doing 3F combination this season is because simply she don't needs to, but she can do them perfect anytime she wants if she wants to. So 3F Mao better. (Mao 1:0 Yuna)
Second, Triple Axel. Mao is the only lady who can do the 3A in the whole world while Yu-Na can't even try it. 3A is the most superior jump of all in ladies. Her 3A is even better than some men. I think everyone know that Mao has best axel in the world. So 3A vs 2A Mao definitely win. (Mao 2:0 Yuna)
Third, Triple Lutz. Mao is not doing 3Lz because she is getting unfair(in my view) judging in CoP. Some say she is flutzing but she is not. It may look like that way because she use mohawk turn when taking off and is so fast and the camera angles can do the trick, but she definitely use outside edge just before take-off same as Yuna and little deeper than Joannie if you look closer. But they suspiciously started to give Mao '!' and even 'e' from some point, when Yuna came to senior level. I'm not suggesting anything but isn't the timing *too* perfect?

Anyway Yuna has been doing 3Lz in competition(a little overscored GEO and looks little bit UR for me IMHO) and Mao hasn't been doing it, so it's impossible to compare or say Yuna's 3Lz is better than Mao now, until she does it again. So I think tie would be fair. (Mao 3:1 Yuna)
Fourth, Triple Loop. Do I have to even bother explaining this?

Mao's triple loop is one of the best no doubt. Yuna can't even do it. She crashed it everytime she tried. Not much of an argument in 3Lo. No doubt Mao better. (Mao 4:1 Yuna)
Fifth, Triple Toe. I think it would be fair to give a tie. I prefer Mao's toe jumps better but they're both doing it well, so draw. (Mao 5:2 Yuna)
Sixth, Triple Salchow. I remeber Mao landing beautiful 3 Salchows in competitions while Yuna fails a lot of her 3S just like at 09 worlds. I heard somewhere that she tends to fail a lot of her 3S in practice too. So I would say Mao better in salchow overall but I'll just give it a tie.(Because I don't wanna get stomped by those crazy Korean fans

) ( Mao 6:3 Yuna )
There is no way that Yuna is better than Mao in jump.
And JOANNIE better than Mao?? OH PLEASE.. that is just ridiculous.

The problem Mao started to struggle is because under this crappy COP, corrupted judges are clearly favoring *certain* players.(I'm not gonna say who

)
Oh by the way, I'm not a crazy Mao fan, I like yuna and Joannie too, just my honest opinion about comparison.
