That's three teams doing it now then! Peng-Zhang, Sui-Han and Antipova-Maisuradze. How exciting!
I wish Antipova-Maisuradze got rid of the sbs doubles though. She used to be a singles skater, not particularly gifted the way the current juniors are (she didn't qualify for Russian nationals) but I did see somewhere on youtube a video of her doing a program with 3T-3T. So I am not sure why they do now double-double combination.
I have to say that I didn't like Antipova's skating last year because she kept regularly looking down on the ice and didn't project at all, but this year it has been fixed and she improved a lot. She is only 15 or 16 so she may not have finished with puberty but if she doesn't grow and doesn't start struggling with her jumps, I can imagine that they could seriously fight with Bazarova-Larionov and Stolbova-Klimov for their spots.
And I think next season Tarasova-Morozov, Gainedt.-Bitch and Davankova-Deputat have to move to seniors. It will be quite overcrowded in Russian pairs on the senior level. I think we will see now Martiusheva-Rogonov and Gerboldt-Enbert less and less.
