Case,
I understand the advantage with 'touch distinguished regulators' as
outlined below. How do you feel concerning 2nd stage malfunctioning
on 1 of the deco regulators ?
If both regulators are identical, you could simply switch 2nd stages.
Otherwise, you might not be able to do so (fitting, IP, etc.). Of course,
if you are using yoke then you could switch the whole regulator.
I assume everybody uses DIN connection on deco/stage bottles,
except for Jess Armantrout for reasons he stated earlier this year :)
