To give credit where credit is due, D/W are fabulous spinners. As much as I love V/M and as much as I think they really are clearly the far, far better team overall, D/W own that element and they own it even when you start to look at the spins that the pairs are doing as well. They don't lose speed and they tend to stay perfectly centered. When so many teams--dance and pairs--can't manage those things, it's really quite impressive.
As far as V/M's dance spins, they have all of the difficulty they need for level 4, but, at times, they tend to travel (badly at CoR) and lose speed.
As for last week, I think V/M were only in Ottawa that one day, and not all of the coaches from Canton were at NHK. There would have been someone "home" for them to work with. Plus, too, I'd imagine it would have been a good chance to work with Swan again.
