Yu Na has made a lot of mistakes in her GP events. I would take a mistake ridden Sasha program over a mistake ridden Yu Na program anyday. It would be interesting if Sasha makes it to the Olympics how her programs would compare to Yu Na and whether Yu Na would still pull those program component scores. The thing Sasha has over all the ladies is beautiful form and carriage on her moves. Even with the falls (and no lady is skating perfect programs) I think she would compare favorably with the top ladies.
