IMO when it comes to skating skills, Yuna and Carolina are just right up there in the stratosphere. Deep edges and speed not lost while skating at all. And it almost seems like they both have no fear of jumps, they're just throwing themselves! What they differ from each other IMO has mainly something to do with choreography and emoting. Carolina has a FABULOUS Bolero LP with intricate choreo, and Yuna has a BEAUTIFUL LP with very much emoting throughout. If you think about it, programs like Bolero wouldn't fit Yuna as well as Caro and vice versa for programs like Les Miserables. They're exquisite in their own style. With Caro putting her technical merit back together, I think it'll be between these two for Sochi OGM. I'm really excited to see these two bring wonderful performances at Worlds, REALLY.
