When I was being examined for my PPL, the examiner decided I had my
head in the cockpit too much. He covered the entire panel with the
largest handkerchief I'd ever seen, and I flew the remaining hour with
no instruments at all. Certainly makes you look outside!

I agree entirely. In fact I teach my primary students how to approach
and land with all instruments covered, including airspeed and
altimeter. If you know the pitch + power combination for every flight
configuration, you don't need much else. However, the pitch+power
combination depends on aircraft weight and load factor. If you use
AOA+power, it would be independent of weight and load factor. This is
why some people prefer AOA. My point was that rarely do we have large
variations in load factor or weight to make this a highly useful
instrument. I would be interested to know if there are any studies that
show than an AOA makes that much difference in stall-spin accidents. In
my observation flying with many pilots, new and old, by the time
someone gets into a dangerously slow airspeed and a screwed up
approach, they are rarely able to pay attention to the flight
instruments or even hear the stall horn. What saves them is their basic
airmanship to recognize the unusual attitude and recover it to a
familiar pitch + power configuration. I doubt that yet another
instrument on the panel is going to be of much help to those who get
that far into the danger zone.
