Those are just my choices, and my reasons. There are many reasons why techniques are in the system... those were just the reasons for my choices...and of course, I'm referring to the techniques AND their extensions, because extra weapons are a GOOD thing...
All the techniques are important, however. They teach different principles of movement. I picked these because they are the ones that I seemed to really click with. I firmly believe that the ENTIRE system should be taught, because I've seen people really click with techniques that I completely struggled with, and to this day don't feel comfortable with. Techniques give you options, and the more options you have, the more likely you are to react with one that is a good one for the situation you're in.
