For me, I've never been a fan of the Zhangs. Altho' at 2006 Olympics, I was amazed at their comeback to skate near perfectly after that horrendous fall on an attempt at a difficult throw jump. With the disruption in that program (and despite their amazing skate afterward), they should not have been placed ahead of their teammates S/Z. I think the judges were as amazed at how Hao sucked it up and skated so well afterward. I think for the Zhangs, they were well-trained and courageous, but also had no choice, since Yao Bin (and their country) expected no less.
Z/Z look very good in their comeback. To me they are obviously inspired by/ copying the style of S/Z. I still don't feel genuine emotion or any connection between them, just practiced emotion and admirable skill. They skated extremely well and deserve to be in first. At this point, I feel since the judges love Z/Z so much, they are bound to win, no matter how well S/S perform in the free. S/S have never been judges' favorite -- it's just that S/S talent level and innovation simply can not be ignored. Judges will do what they can to keep things even, and give more benefit of doubt to V/T, Z/Z, P/T (are they still competing this season?) and name your pick of other Russian pairs over S/S. In order to stay number 1 and prevail in Sochi (if they stay eligible, which they seem focused to do), S/S will have to be superhuman and perform with such magic and precision that skate Gods would strike judges dead for not rewarding them.
