Well, as with most things, there are some varitions on thoughts, and in an
effort to get a "most correct" answer I have compiled the responses so far.
Private e-mail from a list member said:
He felt that if the custom mouthpiece was a danger to the
"receiving" diver, it was definetely non-hagarthian and therefore taboo.

and I agree, This seems like a good postulate, if it is indeed dangerous,
you should not use it.

We don't use them on the scuba regs, as they make get in the way of a clean
exchange , and properly routed hoses don;t tug out you anyway, but they help
hold a rebreather in your mouth when scootering, due to the extra pull from the
big hoses (Sea Cure mouthpieces).
==============
George is saying they do get in the way of a clean exchange, since I only
dive with a "Sea Cure" now, I don't like the implications that I am
endangering my buddy but I don't want to give up the comfort unless
absolutely necessary
==============
Jammer said about an actual out of air emergency:
... and requested the reg in my mouth.
I use a Sea-cure custom mouthpiece, which is way bigger than standard
pieces.
She reported no problems whatsoever.
She said that mouthpieces were definetly not the problem, and she could
have found a way with any mouthpiece I had, as long as it delivered air.
================
Well, here's the difference of opinion. This makes me feel a bit
better about my mouthpiece, but now is it dangerous or not?
==============
A Separate issue is why do you get jaw fatigue?
George said:
The jaw fatigue thing is from gripping too hard - I get it during the deep
air
deco stops , but not when using the normal mixes or normal rigs.
=================
I agree this could give you jaw fatigue, but there are many other
reasons, I actually got the "Sea Cure" mouthpiece with the overbite built
in. After I ruined the first one by pushing it too far in my mouth when I
heated it and "set" it so that it was rubbing against my gums, I then bought
another and left a little space between the mouthpiece and my gums when I
bit down. When I correctly set the mouthpiece, my whole diving experience
became noticably better. I was using a very soft silicone mouthpiece before
my "Sea Cure" and I suffered massive jaw fatigue because I had to bite down
just to keep it in my mouth. So George is right, the fatigue is from the
biting too hard, but if biting hard enough to give jaw fatigue is the only
thing which keeps the reg in your mouth, you bite hard. With the Sea Cure I
can litterally go slack jawed and the reg sits tight. I love it and would
*really* hate to give it up. I definetely could not do a multi-hour dive
with a standard mouthpiece from my experieince.
As you can see I am attatched to my custom mouthpiece and don't want
to let it go. One camp says it is not such a good idea, but someone with
practical experiece says it was no problem. Anyone else out there ever have
to test this in real life?
Thanks for everybodies input.
