Hey George...and all who may fall under the 130'ead spell,
	Is it my understanding that since you were always the first to complete =
your deco before the others due to your advanced knowledge of deco =
minimums that you now feel that the exposures you made beyond 130' on =
air have caused significant damage to your body because of the nitrogen =
density at depth that was hurting your capillaries, or could it be that =
the hastened deco may be to blame?   =20
	You also used to tell us that breathing 100% O2 on the surface was just =
as effective as the 10' stop on air. Do you still think that way? I'll =
bet you don't.
	It amuses me to read some of the twisted remarks you post to user =
groups like this one. Seems all that is needed is a follow up post to =
clear up the discrepancies. Like finding 180' of=20
Depth on the Hydro-Atlantic. At high tide you would need to wallow in =
the rudder washout to hit 174'. Even you spend most of your trimix time =
at around 115'.
	I agree with you on a lot of your views concerning the exposure to high =
narcosis and high pN2 long term effects, however, as you well know some =
are capable of adapting to short exposures and some are not.=20
	One thing I'll never get is why recreational divers have not been =
taught things like the long hose advantage and the use of EAN75- or =
greater for a safer safety stop or emergency deco gas. I guess the =
chambers wouldn't see much diver traffic if this were as common a =
practice as it is in tech diving.=20
	Keep on raggin out the clowns that won't change but remember the facts =
when bitchin in your backyard.

Tom, forget all of the other stuff -let's just look at the only part
that we can legitimately second guess - the use of narcotic mixes in
dive instruction or technical diving.=20

   I have no idea who these divers or instructors are, there are always
a fleet of them on every boat, and none of them are from here. In fact,
I do not believe there is a tech instructor from this town.

   Let's just discuss the 130 aed. Everyone wants to know why nitrox
below the aed of trimix. ?? - G
