Fantastic thread!
Rich, perhaps CJ might be female and all your arguements for penis preservation are lost on the super-spined one! I think we all know what the last thing to pass through CJ's mind will be after an engine failure in the hover!!
TC: the pop up in auto can easily be taught and performed in teetering head helicopters as any agressive push overs would result in very decayed RRPM quite apart from the danger of mast bump and rotor separation. But you have voiced the whole crux of the discussion - entry speed. Quite a safe manouevre (if a little hard to justify for the majority of flying roles) when performed with high entry speed, but akin to kissing your arse, legs, and your penis (where applicable) goodbye from low entry speeds.
