If you are basing off your opponent with your hands via a grab for a take down and c-stepping through his leg or legs, wouldn't the structure of your stance be of less importance?

If you do in fact mean something like osoto gari (see post 38 above), the videos and pics I have seen of JUDO guys doing this does not use a c step at all. the hips are aligned to 11 or 1030 even, the right leg comes straigth through the gap and goes straight back to 430 taking other guys right foot with it.
