Not lately but a couple years back I took an introductory aerobatic
lesson and one of the things I requested was spins. Wow, what an eye
opener. I think we did four or five...basically a couple in each
direction and each one anywhere between 3-5 turns. I managed to screw
up the recovery a couple of times by not releasing opposite rudder once
the rotation stopped.

I'd highly recommend either an introductory aerobatic flight or upset
training where you can recover from spins. It will cost a chunk of
change but it very well could save your life one day. Oh, and the
introductory aerobatic lesson is a ton of fun BTW. Loops, rolls,
hammerheads, spins...oh yeah, I can see how aerobatics is addictive. :-)
