I see a distinct difference though in all of the above cases (with the exception of Massot perhaps), compared to Charlie and Lubov. All of Sale, Pelletier, Volosozhar, Trankov and Savchenko we’re clearly exceptional pair skaters and it was clear that they could do exceptional things with the right partner.
While I think Charlie and Lubov both are excellent pair skaters, I don’t look at them individually and think “ugh, if only they had the right partner”. I think they are both lacking in some qualities to make that happen, and I certainly don’t see it happening together. Actually I see this as a bit of a step down for each of them. Charlie is not as strong a partner as Dylan was (IMO, of course

). Lubov, despite her many abilities that Julianne didn’t have, lacks a vital piece of skill and that is jumping. In my view, Charlie isn’t going to get where he wants with Lubov either because of this. I don’t really see this as a win for either of them.
But no harm in trying I guess, and I welcome more senior pairs in Canada.
