I actually liked her Little Wing program by Hendrix. It was mature and different, and many world commentators appreciated it. But the lack of melody hurt her, and judges weren't to keen on the program.
I agree that Don Juan was not best suited for her. A program which required her to be 100% on to be appreciated.
Her Dvorak Trio SP was nicely done a few years back.
I like David Wilson a lot, but some of previous works before him were in some ways better. I thought her 2004 programs best fitted her, and you can tell how more relax she was:
I think Rochette has a mature, artistic quality to her skating. It's just finding the right programs and music to highlight it properly, and than perhaps her PCS will be boost up (but her jumps gotta be more consistent!)
