I'll underling Pete's experience (from the finest TPS in the free world) and Lynn's experience.

At my Naval TPS class in 1973, our spin lecturer, spun the F4 over 100 times and then one day it went flat for no apparent reason and never came out.   So when he warned us to immediately recover in the A7 if it started to depart.... that's exactly what we did.    Ejection seat, custom fitted helmet, water wings besides.

I fly my beautiful LNC 2 sometimes just to keep the cam shaft lubricated, and always include some slow flight for proficiency.  That's it.  But, I don't recommend long base legs, they're unnecessary and irritating.  Ball centered and slow from max L/D on base to final.  And AOA, AOA, AOA.

If you want to see spins in the LNC2, go watch Wolfgang.... from the ground with binoculars.

If you want spin training, and you should, go do it in a proven spin trainer.
