Great thread,thanks eyrie!

I like oldman's drawings.Notice how close the grappling range is? There's no giant spaces and multiple opponents in the right applications. Kata is not fighting several opponents who take turns attacking.

When doing locks and throws there is usually a strike beforehand. It's very difficult to go straight into a lock on a resisting person.
The technques are not failsafe(in my experience) and to try to force a technique would be a hard lesson learned.
The2nd ammendment, it makes all the others possible. <///<
