Sorry for jumping in, trying to get a hold of Iain/hsm .. can not send PM to him directly as of yet, I am newly here.
Any suggestions ?
Sure: in the spirit of what @rob.mwpropane was alluding to, you could say something about the use of a nitrox stick with a reciprocating compressor…. (ETA: *oil-lubricated* reciprocating compressor. Of course a Rix is a reciprocating compressor too…. If you’re going to poke fun at somebody about being pedantic, you better also be correct when you do it.

They say the best way to get the attention of an expert is not to ask a question but to say something incorrect. It’s not unique to compressors — or scuba diving.

this isn’t really meant to poke fun at @iain/hsm — or, it is, but very gently. I know people can feel the same way about me in my field of expertise. Maybe the difference is that I actually like the sound of my own voice and therefore have no problem spouting endlessly with far more minutia than any human should ever care about…
