This thread has got far too sensible for a Friday - especially given how it started out!

I can't understand why you'd want to waste time (and gas) shutting down the manifold first (although I'm sure someone will tell me).

but when the shit hits the fan the number one priority must be to save as much gas as possible.
It comes down to the procedure that you're taught. Some teach isolating first so that no matter which side the failure is you've immediately protected half your remaining gas. Some, like GUE, try to identify the failure point first and if shutting down that post doesn't sort it then you isolate.

You will lose more gas with the latter approach if the failure isn't the post you shut down first, but the gas planning that you apply means that you're not dependent on having all your gas in any case.
