Don't forget that a tempo change is required. Even if they started with the upbeat music, they would have needed something else to do the MB pattern.
I guess we just have to deal with the fact that P/C aren't power skaters like H/D. Their bread and butter are the ethereal pieces. Why change when the judges love what they're putting out there?
That's fine, but I prefer couples who think outside the box, like C/B and even Hawayek/Baker (and Green/Parsons who will be at the Olympics in 2026).
