Peng/Zhang vs. Sui/Han
Nan Song vs. Han Yan
The decision is based on a formula: 30% of skaters' best national scores + 70% of skaters' best international scores.
I vote for Sui/Han and Han Yan. Han Yan is the handsdown #1. Nan Son should never have been sent to the worlds anyway. Peng/Zhang just do not have the charisma. I don't think they'll score as well as Sui/Han by international judges outside China.
