Michelle Kwan would have been greatly pleased if she had been able to add a difficult triple-triple to her repertoire. She lost the 1998 Olympics to Tara Lipinski's 3Lo+3Lo. In preparation for the 2002 Olympics, knowing she would have to face Irina Slutskaya, Michelle tried to learn a 3F+3T. She attempted in at Skate Canada and fell.
It was a triple lutz/triple loop attempt.

I don't recall that her decision to train the 3Lz/3Lo was in preparation for facing Irina Slutskaya at the Olympics. That sounds like a bit of fluffy fan historical revisionism, in order to credit Michelle for taking the initiative to challenge herself and match Irina's jump difficulty. Again, I'm a Michelle fan, but that's not how I remember it happening. Watch the video and you'll hear Terry Gannon's comments which reference the criticisms that were surrounding Michelle's skating at that time, post Skate America, and which factored in to why she attempted the ill-fated 3Lz/3Lo.
I thought she attempted it at Skate Canada in response to the enormous amount of criticism (which disgusted me at the time, btw) for her win at 2001 Skate America and the oft-repeated criticism that she was playing it safe while her peers (Sarah Hughes, Irina Slutskaya) attempted more difficult jump combinations. It was like the criticism that hailed down on Michelle at 2000 Nationals for going for the easier toeloop instead of the flip in the short program, which she fell on, and then that resulted in her going for the flip in the SP at 2000 Worlds. (Michelle omitted the flip with the toeloop in the SP from 1998 Olympics - 2000 Nationals.)
Both times, Michelle's decision to attempt more difficult elements appeared to stem from public pressure. At times like this throughout her career, since she was the top US lady and a leader in ladies figure skating, Michelle was treated like a pinata that everyone piled on, focusing on her weaknesses (the lack of a difficult or consistent 3/3) instead of crediting her for her unique strengths.
Now it seems like Yu-Na is being the pinata in this thread. Since Yu-Na is the Olympic champion, still competing, still on the podium even after a year off, people are harping on her weaknesses (the absence of a triple loop) and not properly crediting her for her unique strengths (her 3/3, among others).
However, there's a big difference in the criticism that Michelle received then and the criticism that Yu-Na is receiving now. Michelle was criticized for
not doing things that her peers, who were on the podium with her,
were doing--a flip in the SP, a more difficult 3/3 (or doing more than one 3/3). Yu-Na is being criticized for
not doing something that her peers on the podium, are
also not doing--she omits the loop, Kostner omitted the lutz, Ando omitted the flip. And another big difference--Yu-Na still had the most difficult jump combination at Worlds 2011 that no one else was doing.
No skater is perfect. No one has Midori's jumps, Sasha's spins, Michelle's connection with the audience, etc. Yu-Na's ability in each area though...well, I think it's pretty darn good, to say the least. Enough to get her well-deserved wins at the Olympics, Worlds, GPF, etc. But I wouldn't have gotten that impression from reading the last few pages of posts that have nothing to do with Yu-Na news.
