I'm surprised that nobody has brought up the relative risks of full downs in low inertia ships, i.e. Robinsons, vs. everything else.
In the Robinson risk vs. reward department, yeah the landing might not be pretty given the average private or commercial U.S. certificate holder almost certainly has never done a single full down in a Robinson, but at least everyone has a good chance of walking away. Trade that against how many Robinsons do you want to write off in training until people can do the full down part well?
Wait, don't answer that last part, because some wag is going to say "All of them, please!"
