To show the qualities of her skating: 1996 Worlds FS, 1998 Nationals SP, 2004 Nationals FS
To show that she had difficult times, too: 2002 SLC FS
To show her ability to share her emotions with an audience: 2002 SLC Fields of Gold EX
A pre-1996 video could also help to make them understand how she improved...
This is quite hard because there are so many to choose from!
Best performances: 1998 Nationals SP and LP
Most emotional performance: Fields of Gold (2002 Winter Olympics Gala)
Best exhibition: Dante's Prayer
Most important performance (s): 1996 Worlds SP and LP (Her first world title)
Honorable mentions: East of Eden, Dreams of Desdemona, Hands
If I can only take one performance with me on my desert island dvd disc of hers would be her Field of Gold at the Olympics.
To me, it defined her as a human being, it transcend skating, transcend competitions. I cried buckets as a little girl, learned a lot towards life lessons over night.
It was simply unforgettable.
