(Basically we are argumenting of single vs twin in the following mannor: small chance of full failure vs twice small chance of a partial failure....)
Agreed. However, I believe the difference between the two is not significant enough to warrant the expense and complexity of a second turbine. Throw other factors in the mix, such as ease of installation (say in an A-6 Intruder), then it is a different ball game altogether.
Miniflyer your arguments are sound, logical, and well constructed...it is an honor matching wits with you!!
