It's pretty plain that Mai Asada is the weak link on the Japanese side. Emily Hughes is the weakest of the US ladies, but she is stronger than Mai.
Both Sasha and Miki are question marks. As long as Sasha does a SP, she has to be considered a strength (maybe, depending on whether she is doing any training). Miki had an up-and-down season last year. She gave one solid performance, at Cup of Russia, but she bombed at Japanese Nationals and in Torino. It all depends which Miki shows up this season.
Kimmie showed a steady pattern of improvement last season and from reports has been working very hard on her new programs this summer. She and Mao will most likely skate long programs. The question is whether there will be two sets of LPs and just one SP, or two SPs and one LP.
