George, as we discussed in private email, I had considered one important reason
for being 
concerned with your travel/deco. If you dive with a helium mix you want to be
able to 
switch to a non-helium mix (e.g. Air/Nitrox) as early as possible to speed up
the rate of 
Helium offgassing. Buehlmann's tables as well as Hamilton's tables for the
Wakulla 
project were based on that concept. 

If you are forced to pull your deep stops on the Helium mix instead of
non-helium you 
could end up with a significantly longer decompression. Wind and wave action,
as well as 
concern of hypothermia often limit practical decompression times.

Apparently, you consider this position flawed as you don't agree with the
concept of 
accelerated decompression by switching inert gases. I am not qualified to judge
the 
validity of your viewpoint, but I have not seen anyone else challenge the
concept 
therefore I would like the input from other members of the list, possibly
referring me to 
specific studies AGAINST accelerated decompression. 

By the way, the reason why I'm asking questions is because I don't know shit -
so no 
reason for various list-members to waste bandwidth just to tell me that.
