I did TKD for a number of years and also picked up on some Kendo years ago, when I was younger and had a body that wasn't partially broken down. For the amount I was taught, there is the ability to be really technical in poses during a fight scene. I've written them just to see what it would look like, and to me, it reads real boring. Now that could be me, but I'm not sure the need to include, 'by rotating his wrist and forearm halfway clockwise, he was able to pull at the opponent's elbow, pulling down, which offset the other's center of balance....blah blah blah'.
Personally, I think it's just better(and easier)if the majority of the details are glossed over. But then again, I like it when most fight scenes are a recreation of They Live between Roddy Piper and Keith David.
