Until the AD was issued as of late, I was incorporating a very tame spin into PPL training when we hit spin awareness for discussion. Of course, not being a sociopath, I asked the student beforehand if they would be interested in seeing one and wouldn't press the issue for those wanting to stay away from it.

Needless to say, I find it extremely valuable in training curriculum and find my student pilots have a much higher degree of knowledge pertaining to load factor, cross-controlled coordination, and the relationship of stall speed to bank angle, maintaining less than 30 degrees in the pattern and so on...

Like others said, its definitely not something I want to 'experiment' with. My power-off, no flaps, one turn around is good enough for me.
