I'd have to agree with Peter. Conceptualising about technques is missing the point of aikido slightly, although I do feel it is useful. The best way to conceptualise is to look at the grading syllabus. The way the techniques are organised says a great deal about the stress the sensei puts on different facets of aikido.
For example, in my old club, we did lots of pins (ikkoy, nikkyo etc) from katate dori (wrist grab) at the start. This was usually from stationary. They stressed power and good centering.
With my new affiliation, the syllabus starts with kokyu-nage, irimi-nage and tenkan ikkyo. They stress timing.
