I have to say i quite like the concept of the amber/red/green thing. Its short, to the point and raises awareness about a pontential problem. Sometimes things can get hectic in not quite normal situations and workload can spike. Not a bad idea at all.
The other stuff is of course, well, not really a good thing in my book, verbatim reading of very long take off briefs pose no purpose except as a CYA exercise for the CVR. I'd rather have a short briefing that highlights the important points.
