Subject: Argox for safer deco?

This recent talk about o2 window, N2/He gradients,
and the deco issues with 100% O2 got me thinking 
about using Argox for the 20/10ft stops.

I've heard of Argox basically being used as an 
experimental deco gas, but not regularly or seriously.

Anybody know why?  In theory, Argox should give
all the advantages of deco on 100% O2, while
totally eliminating O2 toxicity concerns. 

And if you're a believer in bubble mechanics,
it would allow you to pull even really long
decos at 20ft without raising your CNS clock
much at all (vs. hitting 100% of your clock
after 45 mins on pure O2).   An Argox 50 would
give a PO2 of about .8 at 20ft.
