well- that wasn't precisely what I was getting at, though I do understand a desire to have varying degrees of energy.
The lead in questions wasn't doing moves that I would call flashy or show tango-y, but he was applying lots of energy to every move he made, even simple turns, without any variation at all, to partners who weren't really responding to it (for whatever reason).
I prefer to try to match the energy level I get from a leader. I enjoy leads who play with the energy level, but higher energy just doesn't automatically equate to big or flash and trash movement. If so, then I think one of the important points of the dance has been lost (IMO at least). You should be able to apply varying degrees of dynamic to any move you make, and it doesn't mean that the move has to develop in to a space eating monster because of it either.
Here is a video I've posted before, because it is small space dance movement, in close embrace, and it is (IMO at least) not in the least bit "lazy". They appear thoroughly engaged.There are slower movements, faster movements and timing changes, a couple of sharp level changes and interesting footwork and embellishments (esp during the variacion), without taking up huge amounts of space or devolving into the tango "flash and trash" that most people seem to equate with dynamic dancing.
