So far this seems to be a junior skater phenomenon. Both Michelle at 15 and Tara at 15 were super little jumping beans. But I don't think that either one of them added much to their jump reportoire after age 17 or so. Sasha at 17 practiced a quad along with several triple/triples. When she stopped doing that and concentrated instead on her
skating she shot up the senior ranks like a rocket. All of these Japanese girls are 16 or younger.
So it seems to be a natural progression that young ladies jump, jump, jump as juniors; then as they reach physical and artistic maturity, other aspects of their skating come to the fore. Yoshie Onda is a good example of a skater who was all jump a year or two ago, and is just now developing some grace and artistry to go along with it. I think that she has stopped trying the triple Axel.
When Michelle

won the 2003 world championship she was light years ahead of the field, even though she did only a 6-triple program with no quad, no triple Axel, and no triple/triple. I think that's a good sign that the sport still requires a proper balance between athleticism and grace.
Sasha has not so much as attempted a triple/triple this season, but her overall skating has given her 197 points in each of her Grand Prix events, based on the overall quality of her skating.

Ladskater, my curiosity is killing me, I just have to ask: Why does the Sunset Dental Care web site host a beautiful picture of Yuka Sato?
