Yuna Aoki had questionable lutz edge the last time I saw her. But it is to be expected because she's a girl and girl has hips which make it troublesome for the lutz.
Her Axel is very very great though. What a pity she has been struggling for quite a while.
And yes, I think people misunderstand something when it comes to Yuzuru's jump technique. There has been a thread on Baidu where Chinese fans posted slow motion gifs of Yuzuru's jumps when he was a kid compared to his GPF 2015 technique. Yuzuru already had great pick up technique when he was a 10 years old kid. No pre-rotation whatsoever. That time he was still with Mr. Tsuzuki. If anyone should get credits for Yuzuru's amazing basic, it should be this man.
But I have to say, Yuzuru's current correct Flip jump was thanked to the time he trains at Cricket Club. Before he used to get a lot edge call for the Lip. But since 2015, his FLip has gotten very much better. For example, a very good and correct Flip here:

And it is not wrong to say Yuzuru's quad Sal is also from Cricket Club.
