Donna, when I hear you talking abt how complicated some art is, I sympathize immediately.
I felt the same thing in the unarmed arts, where there are literally hundreds of techniques, all of which nobody really knows if they will help in an actual encounter.
Then if you waste time and effort learning it, it's even more upsetting
But if you go to a typical "karate" or "judo" tournament, you will see the people there at best only using a few techniques, eg
reverse punch, backfist, frontleg roundhouse kick, sidekick for karate, osoto-gari, ashiwaza etc for judo. It is how these buggers apply the techniques that lets them win.
One book that expresses all this really well is called "Secrets of Championship Karate" by a girl called Karyn Turner(Contemporary Books, Chicago). She was a student of somebody called Dacascos and did well in tournament karate fighting. Her book attempts to explain the basic principles of how to overcome an opponent in a tournament situation.
I think what is in the book can be applied to any MA situation, whether with weapons or not. There is a lot of stuff abt speed, timing, distancing, evasion and angling. Also on simplicity of technique.
It is the best book I have ever read abt point-fighting in karate competitions. I know what she says is true because it is also my personal experience. I wish I had read it as a young boy, instead of 8 years ago when I was no longer interested in MA.
Best wishes from SYK
