Yes, I do understand what you say and I don't think that Lambiel is a bad choice but he doesn't strike me as someone who has such a different voice from theirs (and that might be why they chose him too).
Lambiel is a solid choreographer, but I had the same thought that he might produce what we've come to expect from them, especially with the style of music they've chosen. I guess I wanted something very different from "typically G&G's style" but that's my problem, not theirs. I do think it's easier to convince both judges and fans that you're evolving with a dramatically different look and sound from the previous season, like Stepanova/Bukin did.
