I see the value in both. I know we've disagreed about "high noon" exercises in the past, but from my experience of social violence there is a lot of waiting for someone to move involved. When I talk about "high noon" though, I'm actually talking about hands-down gunslinging toe-to-toe, not two people in some kind of "martial" stance waiting for a command to move. It's the aggressor picking the moment, and the anticipation of the defender that I find useful. Church bells tolling, a bead of sweat running down your brow... all of that Anyway, as to the kind of thing I think you are on about, again free and fixed footwork. I'm all about permutations, and most often this kind of thing comes out of me seeing someone get caught out a few times by the same combination of moves in sparring. I'll get the person getting caught out to formulate a response, then it will go from a recreation of the footwork used to free footwork and working different angles, ranges etc.. If we get into it then we'll switch out techniques and other variables, possibly giving a few options of moves rather than entirely prescribed. On the rare occasion I'll dictate a set of moves (never more than 2 techniques each), then the footwork will be free, so that angles, range and timing are all part of the exercise. I see it as like a fixed pad sequence, but with a person.
