So true....

I don't know what the fuss is all about. My pit crew takes care of the pressure

What do you consider very wet? I'm looking at Praxair's spec sheet:

http://www.praxair.com/~/media/praxa...4631.pdf?la=en

what's 'wet'? 5 ppm? 1 ppm?
The 'wet' definition depends on purpose. The chemists that used nitrogen for their reaction anhydrous atmospheres back in graduate school deemed less than 0.5 ppm dry while the experimental physicists deemed less than 3 ppb dry.

So it depends on usage. May I ask what your usage is?
