Finally!  Back on techdiver!

I saw a show on the tellie the other night about DCS in commercial
divers, primarily in the North Sea.  They discussed at length the
differences between normal deco stops in the rough seas, and 
coming directly to the surface for surface deco in a chamber.

Granted the show was a little dated, but they made several
remarks that indicated heliox was a much better gas mix for
deep diving than trimix... i.e., ANY nitrogen in the gas mix
was bad.

Not having read through my book on Mixed Gases, I thought I'd
ask the experts here.  Is NO nitrogen better than a tiny bit?
