You are of course spot on.
That’s the point, more comfortable.
Sometimes carrying a spare engine WILL be helpful. Like your case.
Quite right you feel more comfortable.
Much nicer to fly home than to swim to shore.
You must take that upside and weigh it against the downsides.
Against the ONE HUNDRED TIMES MORE PROBABLE likely causes of your death.
Your comfort from the spare engine needs to outweigh the downsides.
If it does 'you’re good'.
It needs to outweigh the chance that a freewheel unit will let go and tear off your gearbox and rotor head. That the overcomplicated gearbox doesn’t break and leave you without counter gravitational support. (poor sods). Your hydraulically assisted tail rotor (why does it need to be hydraulically assisted?) doesn’t force full travel and leave you like my friend in Leicester.
When those things happen you don’t get to swim to the bank, but you’d wish (briefly, as you remember this post) you could be given the chance instead to simply autorotate.
make sense?
