Even 2 man choreographed sets serve a purpose beyond show. You are training your techniques, your timing and speed. You are training angles and distances, and you get a sense of what it is like when you are being attacked by another weapon.

Just wanted to fuel this debate up again. I still think some of the bagua weapons sets are using weapons that are practical for street defense. Sets like elbow dagger's, needles, and judges pens since these weapons can be easily carried, concealed and effective.
