Chen, Uno, Kolyada, Hanyu I see for sure. I dont see Boyang making it since his assignments are super tough. I see his max placement being 2nd at best, but could easily see him being 3rd or lower in both too. Zhou has decent assignments, I could see him coming 2nd at both and making it. Aliev also has decent assignments, he could potentially be 2nd in both, and even a 2nd and 3rd might make it.
So I pick Chen, Uno, Kolyada, Hanyu, Aliev, and Zhou.
