The problem I see with flying both types is the fact that control inputs are reversed. People say 'you get used to it' but in an emergency situation eg EFATO instincts take over; it's already killed several experienced people including instructors. eg Long Marston about
'91-ish; experienced 3-axis instructor in a flex wing; engine failed on climbout; he pushed forward instead of pulling back and it stalled in and killed both of them.
