I say no to air taught for use beyond 100 feet. I believe PADI already
wants its divers to get its "Deep Diver" specialty to go below 60 feet <g>.
 It could not hurt IANTD to follow their logic and begin hyperoxic trimix
as the gas for 100 to 175. 

As to Wrolf's comments, when Wrolf is on the opposite side of an issue with
us, the world is a much more "ordered" place. Right on one side ( us),
wrong and stupid on the other side.  I found it comforting to see Wrolf
"wants" deep air <g>.
