Well, if i can have my 2 cents....

Now, the show prompted me to
consider taking some sort of spinning and recovering training. Am I being
overacting or paranoid?

I am not an airplane pilot, but a glider pilot, and I have done my training
in France, even if I have flown a couple of hours in the US. In my training,
spin was mandatory, and my instructor, before my solo, asked me to do 3 full
revolutions in a spin, and exit on a pre-determined axe. Certainly, a glider
is less impressive than an heavy plane and rotate relatively slower, but,
that's not the point.

When you fly sailplane, while you spiral in a lift, you are constanly
flirting with stalling, as the goal is to fly at the maximum lift
incidence/speed, which is a couple knots above stall, and when you are busy
trying to center as well as possible that anemic thermal, your speed is not
always perfect.

All that to say that I stalled (dissymetric, being in turn) many times with
my Standard Austria ( not the SHK ), as this sailplane is known to not like
too much slow speed, but i NEVER did more than an half rotation, losing less
than a hundred feet each time, as I do believe that if you know the signs
annonciating a stall, and react immediatly, most of the time you will not
even stall. (I also did many 300 kilometers circuits with my Austria)

All the above to say that, maybe, your best training would be to fly
sailplane, as you will know how to get out of a stall as fast as possible,
and flirt with the limits a lot more than you are used to in your airplane.
