I'm very much for spin training, be it during the PPL or after, it allows pilots to experience extreme manoeuvre and be confident of recoery should it ever happen. The increased confidence alone is worth it.
However, there is a very compelling argument to keep it out of the PPL sylabus in that most of the loss of control accidents were at low altitude, certainly too low for recovery from a spin. Therefore, as I understand it, it was decided that slow flight and spin avoidance training were worth more in flight safety terms than spin recovery.
It's a moot point, but the statistics would appear to support current practice.
Notwithstanding, and I'm nothing to do with UH (although I do know some of their pilots), but I would commend any pilot to do a spinning (and aerobatic) course, no matter what aircraft he or she flies.
