Well, I really thought the Shibutanis were undermarked in the last Jr worlds. And I believe that, while I do like I/K more, the Shibs are wonderful and the most prepared of all the junior teams coming to seniors this season. Still, to their defense, I/K are skating together since 2008-2009.(and P/I since 2009)
B/S are for now the best russian team, that's clear, but my fear is that evan if I/K will improve over time, they will never ever pass B/S(with Tatiana Tarasova favoring B/S) a It's probably to early to make any prediction, plus,with Monko/Khaliavin in the mix next season, you never know!
