Re: Aikido vs....
Well I know what you mean but there are limits right. You don't expect people to invent shiho nage for themselves right? You show them the basic form and then add details when they're ready. Same thing here. You're expecting people to discover upa (escape from underneath the full mount) for themselves from aiki principals, when it would make more sense to have someone show it to them, at least in broad strokes.
