Thanks to everyone on the list for input.  Last Sunday and Monday I actually
did two gas dives with two interleaved air dives on the Andrea Doria, all in
the 200-230 fsw range.  I wasn't fully comfortable with using the Aladin Pro
as I described in my note, since I was concerned about the possibility of
existing bubbles from the trimix dive growing during the air dive in ways
that were not accounted for by the Buhlmann alg.  

What I did was to use the DECOM program to cut trimix 18/40 tables, and then
accelerated air with EAN80 deco repetitive tables (I certify that I am not a
paid representative of Ronnie Bell - in fact I forgot that he was involved
with DECOM or would have emailed him some questions).   My Aladin got bent on
every dive, but my buddy and I are fine.

For anyone that might be planning to do this wreck, I would recommend air for
dives outside the wreck that don't go well below 200.  Under conditions we
had - pretty good vis, but strong currents, you are probably better off
without multiple stage bottles but with a little bit of narcosis.  If you
want to go in, however, I would advise gas, especially because you are out of
the current and won't be carrying stages inside.  On three of the four dives
we went in to explore the second class dining area.   This involves a couple
of turns, and going down stairs two decks.  The gas dives were pretty
straightforward but the became very confusing on air at 210 fsw!
