Drew:  I don't use an AIR2 and wouldn't consider it but I was wondering about
this statement about redundancy between drysuit hose and BC inflator hose.  Is
there anyone out there who has actually done this in practice?

I for one have tested the positioning of my BC inflator hose vis a vis my
drysuit inflator valve and I'm pretty certain that there is no realistic way
that I could pull my BC inflator hose off and attach it to my drysuit inflator
without getting at least half way out of my harness.  First of all, my drysuit
inflator valve angles down and to the right to connect to my argon hose or
regulator drysuit inflator hose coming from under my left arm.  So not only
does my BC inflator hose need to reach the drysuit inflator valve, it would
need to kink around nearly 180 degrees to attach to the nipple.  Following the
instruction of my DIR cave instructor I shortened up my BC inflator hose and I
just don't see where attaching the BC inflator hose to the drysuit is a
realistic option unless you have a really long inflator hose to begin with.
My hose is long enough to reach the drysuit inflator, it's just not long
enough to make the 180 degree kink to attach to the nipple.

As for the opposite, why would you ever disconnect your drysuit hose and
attach it to your BC?  It's much faster and more straight forward to just
orally inflate in the event that your power inflator fails which is what my
first response to a power inflator failure would be.  Is there some reason why
emergency oral inflation of your wing is a bad idea?  Heck, oral inflation
used to be the ONLY way to inflate wings and drysuits.
