Julia has of course some problems to fix, but for sure not with weight gain (unlike Liza). Look at her:

what about OG-2018 "sborna" prediction I have no idea, but I think the best mental features for that have: Evgenia, Radio, Anna and... Maria Sotskova
I really think Julia will not resurface as the it girl in Russia. Her tiny body helped her become that girl. I don't think she can overcome the weight gain. Her body has betrayed her.
Well from reading her fan fest and articles since her switch to Urmanov: There's a more structured physical conditioning routine which is going to aid her in being in better shape and she openly admitted that she is enjoying FS more now, which probably results in her working more/harder in practices and training. She showed up to Cup of Russia after Nationals with a new FS dress because the old one was too big on her. What also probably helps her immensley is that she has a good technical coach in Urmanov and he does not have the volume of students that Eteri does and he can give more focus to Lipnitskaia.
