My Stemme has built-in AoA indication but it's on the EFIS and I'm
looking outside during the pattern. All you really need is to be able
to recognize sloppy controls, reduced noise, and uncommanded movement of
the nose. This has been discussed to death (no pun intended). There's
no instrument that can protect you as well as training and practice and,
if you need to rely on an instrument, maybe you should be keeping
tropical fish instead of flying.

You can stall and spin from any attitude or airspeed. All you have to
do is plan and execute it correctly or simply f*ck up the turn.

An AOPA article states that the AOPA Safety Institute and University of North Dakota are studying the "circular vs rectangular" pattern as a result of the NTSB "Most Wanted Safety Improvements. It'll be interesting to see what the study produces.

It's REALLY hard to spin while flying coordinated - if you know of a way I would truly like to know. It is also tough to stall while flying coordinated because it takes a very high angle of attack and you would really have to work it keeping the glider coordinated as you approach stall. The FAA is emphasizing an angle of attack indicator to prevent spins; I think what is needed is an audible flight coordination indicator. In our gliders we have a heads-up flight coordination indicator which is even better - it's called a yaw string (but you have to look at it and react to it).

I rely on my instruments EVERY time I fly, especially in the landing phase; don't you? Training and practice are a good thing, but they CAN'T substitute for good instruments, only teach us to use them properly. One can compensate for the loss of an instrument, like airspeed, but one would not deliberately not pay attention to a working ASI in the landing phase.
I, too, have an AOA; it is the artificial horizon in my Air Avionics (aka Butterfly) vario. I do not find it particularly helpful. I prefer to monitor the real-time wind indicator instead. I also assume that you pay attention to wind socks...
