Looking at Liza's last competition, where she won nationals:

First of all, she looked really sick out there, and I was hoping that she would go home, take a warm bath, drink hot cocoa, and go to sleep.
But she's a fighter, she gutted it out, and finally became Russia's champ, YAY!
In some ways, given her condition of course, it looked a little perfunctory, like she was going through the motions, just to survive. But one thing is for sure- her technique by now, honed by Mishin, is rock solid, dead rock solid. I mean, looked at her lutzes, and her double axels, where she doesn't pull through with her arms, but drives through with pure power from her hips.
I don't think she needs a triple axel- her PCS will rise, her ice coverage will improve, but she has those beautiful jumps, esp. those lutzes. And as Wallylutz pointed out in his analysis (can't remember the thread), a girl with solid lutzes has big advantages over those who don't. With all the big players in Sochi ( I thought she had a great chance, but now prolly Yuna, Caro, Mao, Ash, have better chances), going for a triple axel may still be a risk, because it might divert needed attention and energy from other aspects of her skating, like her spins, for example. Liza doesn't have great layback, never points her foot, has no bielmann, but has good variety and interesting positions. These can be worked on and improved. But that triple axel risk, esp. now that her body has changed, may be more like a gamble. I think her best chance is to be like Yuna- try to get as high consistency and hit rate on those pristine jumps as possible, while improving all other aspects of her skating. The judges can't ignore that, they'd be crazy.
