OK you got me there Marv, I have not dove double AL 80's, guilty as charged.
I do have a set of HP100's which are bad enough, I cannot imagine why I
would want to get even worse with a swing from negative to positive. Sure
you can dive AL80. How? Add lead. You seem to have an issue with me having
"too much air." This is silly. How can you have too much air? Are you saying
that this is like going to a liquor store and purchasing a pint rather than
a fifth to avoid a hangover?

And I have to say that I could not care less what GUE, DIR or whatever says
about what kind of tanks you should have. My goal is to be neutral at depth
without the use of a weightbelt so I won't be a NE anchor diver. That goal
accomplished I have to say it's a great way to dive. The concept of diving
without a weight belt really fucks with some peoples head for some reason. I
guess it's a "hangover" from their PADI, NAUI days where rec training
dictates weightbelt=salvation.

Well you can throw this shit out the door for tech diving. And as far as
GUE/DIR is concerned when we had some well known DIR guests up to visit did
they ask for us to provide AL80 doubles? Shit no, they wanted Steel tanks
and Vweights. And I can't say I blamed them and their dives went flawlessly.

And I'm glad that you found the "brass fever" post disconcerting. It was
meant to be disconcerting. I'm glad that all your dives go perfectly and
that you have never made a mistake, you are one hell of a diver, that's all
I can say. Me? I'm fallible and in this case made the correct decisions
after I got in trouble and survived the dive, which was the whole point. I
would not have been able to make the post had I not.

When in FL a couple of years ago guess what rig I dove? What I always dive,
steel doubles, AL40 stages. And in FL part of the dive is floating around on
the surface waiting for the boat to come pick you up. I had no problem doing
this.

Al, I know you have AL80s and like diving them. But you seem to be trying to
make some sort of point here and I just don't get it.

   Jim
