Matveeva didn't impressed me last year. I find her a bit slow and her sets are predictable. But then, she's young so there's room for improvement and she's tall too, so that's an advantage.
For the OHs, I wonder why Parubets and Kadochkina weren't included? I'm curious how this pair would work like how Voronkova-Fedorovtseva duo went well last year.
Also wondering why Suvorova wasn't on this list. I'd also like to see Brovkina, Sergeeva, Gorbunova, Pipunryova, and Smirnova. (Probably playing for the opposing teams?)
I think Matveeva is pretty solid but I like Kobzar and Popova more.
Parubets, Smirnova and Kadochkina will play in the Kaliningrad team. Suvarova and Sergeeva in team Tatarstan, Pipunyrova Moscow, Gorbunova Saint Petersburg.
