I'm not being facetious, but spin recovery is not really the issue. It's about NOT getting into a spin in the first place.
This means (for one example) a more intuitive understanding of AoA than you probably have/had as a low houred PPL.
blockages, single engine failures, hydraulic leaks, instrument failures
None of these should end in a spin (Genghis, I understand that you would realise this - I'm trying to clarify for Hour Builder).
I'd suggest reading The Killing Zone if you haven't already. That contains most of the common ways pilots manage to turn survivable emergencies into fatalities.
