With Parubets not making it to Tokyo, I think Russia's OH roster is now more or less set: Voronkova, Fedorovtseva, Kosheleva & Smirnova (Smirnova can do both attack and reception duties, but of course not as efficient as Parubets). Only remaining question mark is the 3rd MB and Goncharova's backup (most likely Lazareva).
And the 2nd setter.
