Hence why now is the worst time to make a decision like this. But oh well, hopefully she'll be fine.
My only concern is that given Pluschenko's position now of having to prove his excellence through Trusova, if her progress will no appear satisfactory to him or fast enough, in order not to "lose face" Plusch will not be patient and may run her into the ground or will allow Trusova to jump her self to the end of time..
If this poaching stunt does not work out for Plusch (who is seeking skating and ego related success) and Rudkovskaya (who is the boss and is seeking publicity, promotion of their school, and ultimately money), his reputation will be damaged.
Plusch/Rudkovskaya attacked a lot of people in FS this past year, in quite serious and nasty ways - Yaguding, Zhulin, Tarasova, Tutberidze, Averbuch, Tarakanova, various persons in the federation and FS world in general. He has very little friends now... maybe those only who depend on him or Mishin...

Plush wants to stick it to all now...
Rukhin leaving .......................

There is an old Russian saying -
Баба с возу - кабыле легче.
"Wench is off the (firewood) cart - (makes it) easier on the mare".
He is 16... his highest scores and best results as little far as 6-7 months are these..
He can either transfer to Seniors now, and realistically, to never medal at major events or certainly not make the Russian Oly team. Or, he can stay 2 more years in Juniors and still not likely to medal at major events or make the next Olys. TeamTut certainly does NOT need Rukhin to add doubt to their reputation and issue with "men are harder to train".
By the way... it was Rozanov who supervised and trained Rukhin all this time....
I, due to some internal gut feeling, suspect that Rukhin is either a fantasy-dreamer (about having his performance greatly improving with the "same coach, but in a different rink 1 year before Olys"; or he in reality does not have very high expectations in results in future competitions, but was promised a lot of "off the ice benefits" (higher stipend, trip to Bulgaria for summer camps vs. hard core Novogorsk, and like Pluschenko likes to brag - more sponsors and publicity, etc).
While for these skaters (Rikh, Trus, Zhils) is about their skating and results and have to some extend "legitimate purposes when it comes to skating", for Pluschenko, and more for Ruskovskaya - all of this are "their own agendas and power trips and revenge and egos".
Rozanov is not stupid... he sees all this too.... he also has ego... and if he was given a free pick of any top young skater to train, Rikh and Zhils would not be his picks (exception perhaps Trus, but she has also limitations for now).
Good luck to skaters - they are doing it for the right reasons; and may Karma come to Plusch, Rudkovskaya and Rozanov for their actions (which could be good for helping skating, or it could be bad for blind selfishness and destruction of skaters' future).
