@jhull is always gonna say a Z pattern is most effective. It's the linear in him. Being a tad more holistic myself, I recommend you use the quad in the order that makes sense for the FEELING you want to create. I think Jim is working on a way to re-order the InstaScene.
One of my evidentiary pieces is the order of the Pixar (academy award winning) short Piper.
Piper is in the stratgey quad. and goes (Inaction-->Reaction-->-Protection-->Proaction)
A z pattern for that quad would be (Proaction-->Inaction-->Protection-->Reaction)
which would be ALL WRONG for Piper.
So, just go with the order that works for the story and feeling you have in mind
