Wait, you haven't watched Eunsoo this season??? Her SP is the best SP so far! Just absolutely stunning!!! She skated in the Asian Open.
I have! It was awesome But still, there are skaters who skate in Challengers and then choose JGP. I'm glad it's not the case with Eunsoo. She's a senior level skater, and this way the youngsters have a chance to compete in JGP
ETA: Just saw that Sophia Schaller, who competed here, is on the entries list to Finlandia Trophy. That's just an example of doing Challengers and JGP.
