personally I don't mind too much if you use stroke thoughts or focal points.
To me te real point is that those bullet point one liners have to be sustained by a thorough explanation of what they actually stand for.
It was very interesting to hear about the genesis of zen switch, zipper switch, swing switch.
What I'm saying is that while a single line catch phrase maybe be easier to memorize I much rather rely and recall the thoruoghly explained reasons behind it.
That way you'd never have to go through the motion times and times again like westywood so well pointed out.
I'd say extended explanations first and only then focal points/stroke thoughts
