Vorticey, I told you I'm not the author of the vortex/circulation theory but what you describe is what the theory suggests ie that a vortex is formed at the root, tip and the trailing edge - giving a horseshoe shape. When you pull the wing through the water/air it leaves the trailing edge vortex behind it, parallel to the trailing edge itself. When you stall the wing and break the circulation the vortex isn't left behind any more and it catches up with the wing.
As for the rest, you said 'pressure' as well so you will probably be ex-pprunicated and banished to the wilderness, even though I agree that most of what we have been talking about on this thread is pressure related.........Oh no, now I've said it again!
