Yes, this would be OK, I hope that people from Federation have the same way of thinking.
I prefer I&Z's style to stay at home - I refuse to think that Zueva is the only one who can say whether skaters have potential, it can do anybody from top Russian coaches in Russia, there is no reason why to come to US and for three weeks to see whether they are compatible. Kustarova is great choice - and it would be much better to send BOTH teams to her for tryouts and then decide (and tryouts could last few days only). And there is already first problem, while I&Z will be judged by whole Federation and by everybody who will come to practise in Moscow and their progress will be under control from the first week, S&K will be judges firstly by Zueva (after three weeks of work + those tryouts before the whole world discovered that they are a new couple), and believe me that she will talk in superlatives, so her words will look stronger than those words Kustarova said, in the same moment Zueva will be no idea how is I&Z, so no comparison here), than S&K will be judges by specialists who will be already influnced by Zueva's words. If Russian Federation really wanted some tryout period for only looking for compatibility, working ethic and speed of learning new elements...than make those couple separate and give them different possibilities is not the most wise. And if this is just tryout and Nikita persist on Zueva and Federation agreed, so why not immediately from the beginning listen to Nikita in everything and making this team official, when Nikita wants it. How do you want to control training process and watch progress in couple when they are three weeks off...and Zueva knows her job very well, but she has their own motives to support promising couple and no possibility to compare with I&Z, and right now even no possibility to compare with another top Russian couples. So, already from the beginning this is far to objective to make any wise conclusion. Why Russian Federation just couldn't put both new couples on one place with one coach for three days, with three practises per day...and then just decide - yes, no...and let people work and prepare for next season?
