Maybe, (with regards spin training) but some of these aircraft havent demonstrated spin recovery during their certification and like many things i am not convinced of the value of training unless it is cojoined with currency. I still fly aeros enough but i know after a few months of missing them a deliberate spin is still interesting - then again i am probably just getting old. Still if push comes to shove i would prefer the pilot pulls the handle than rely on a few hours of spin training five years ago.
