Maria's comments lead me to a key differentiator between "technical"
and "recreational" diving.  

Technical diving always involves a specific goal.
Sport diving often has no purpose other than enjoyment.

This key difference sums it up for me.  Without a specific goal in
mind, I certainly wouldn't be doing long deep dives which require
decompression.  Without a clear goal, I'd find another area to dive
which didn't have the same burden, and turn the dive back into a sport dive.

Ah, but if you were using EANx in the proper depth ranges you'd
probably not have gotten into that mild decompression.

In my climate -- Monterey Bay with 50-55F water temps, and rough open
ocean conditions -- my "technical" dives are all deeper than 130fsw.
I can safely use EANx only as a decompression mix.

I, too, find the added equipment maintenance burden of Nitrox
inappropriate.  However, were I doing dives in the 100-130fsw range, I
would find the reduced decompression obligations of EANx most
enticing.
