The spare engine is useful ALL of the time since it is not a spare but permits greater capability from the aircraft ( AUM, payload, speed etc) than a single engine helicopter.How many 6 to 8 tonne single engined, helicopters are there btw?

I'm not sure you are right there.
Have you considered the Bell 214 v Bell 212 for example?
Or the AS350 v AS 355?

The reason there are not many heavier twin types made is most likely due to the regulations requiring twins...
Ever thought why the K-MAX only has one engine?
