I don't think it's a good idea for Ilia to go for the quad axel or quad lutz in the TE short. Especially if he hasn't changed the choreography. The entry into the axel is very cool as it is and it really works with the music. But, I would think that it makes the quad axel even harder. (Plus, it didn't work when he tried it in competition before.) And, I like the spread eagle into the flip which probably increases the GOE on that jump. Also, if I recall correctly, the lutz and the axel are the only quads that aren't worth more than twice as much the triples of the same type. I don't think the risk is worth the reward. If he uses the original layout, he is so much more likely to finish in first, and he doesn't need to change the layout to finish in first.
If he really wants to do a quad axel, do it in the long program.
Maybe they're just playing mind games with the Japanese. But, if I were the Japanese, this announcement probably would make me feel better. It's the best chance for the Japanese to get more points than the Americans in this segment.
If he really is doing this and risking points for the team, I sure hope this means he has agreed to do the long program if he doesn't do well.
