Are you really serious? I&Z have sloppy edges and GP and C&B UK (the two teams with the weakest technique) should've been ahead of them?! I&Z might be a new team but these two are head and shoulders above G&P and C&B who simply do not have the quality required in their skating. I have sympathy for C&B in particular and they have their tricks to show their best but they are more like Pairs rather than dance. I can't imagine you are even comparing them with I&Z. The only thing that I&Z were overscored was on that crappy FD choreography (some 9's they received were lol). The fact is they were underscored twice last season. In CoC, both on the SD&FD, they should've placed above C&L and in the SD portion at the Europeans.
Shibs are very good skaters indeed. They have great posture and SS but why do you think I&Z should've been behind them in the SD at world? If we can call that being ahead since practically they received almost the same scores. The difference was nothing.
I don't get your criticism about I&Z step sequence tbh. Their step sequences are a perfect example in order to understand how good their SS are. They have deep edges. There is flowin their skating and all the speed is generated by the blades. They have very good knee bending and posture. There is no pushing by lunging forward atthe waist or toe pushing.
About the dance holds I'm not sure I understand your complain. You mean they were not so many and not close enough or that was something wrong they did?
Obviously the choreo is on Igor. It goes without saying that if we criticise a program it's not the skaters fault.
What do you mean that she seems oblivious to her partner's level and style? I think they have done a tremendous job in terms of matching and looking like a team in such a short time. Ruslan has grown immensely because it helps a lot when you have a good partner and you don't suffer from vanity.
