Chuck, the other consideration is terrain. My operating environment, like many, is rather hilly/boggy/full of small fields with dry stone walls. An engine failure and subsequent forced landing would almost certainly result in a very bent aircraft. To manage the risk to the point where I could always guarantee a totally viable forced landing site would make the whole concept of single-engine untenable.
I'm about 30 years short of your 50+ and have yet to suffer a failure in an SEP. That doesn't stop me thinking about the scenario though.
