its probably because @Nailbender hasn't responded in a few days :).
For me, I'll stick with the "narrower" definition, ie World Cup moguls, but I don't think that should derail this thread.
To me, all mogul skiing is hallmarked by active A and E, with the both the range and the quickness dictated by both terrain and line choice. Outside of mogul terrain there just is not the need for this range of motion, or certainly not at the same frequency and magnitude.
I suspect if a great many of skied moguls together, our actual *skiing* would be much more similar than the words we use to describe it.
I'm getting 3-4 days in yet at Abasin this coming Sat-Tuesday.
