Hi All,

I'm not John and I am not going to dispute DIR, it is a very good thought 
out and proven system. Although there are other teams doing some interesting 
stuff without adopting DIR, it does not invalidate DIR in anyway and visa 
versa. People dive DIR or they don't. I have adopted some bits of DIR, but 
am not DIR and do not intend to be. I'm far more interested in being 
underwater than worrying about it.

Steel tanks though... In the US you have these monstrosities called "low 
pressure steel tanks" i.e. 180 bar. They are very negative. You'd be silly 
to dive in a 3 mil short with them coz you'll sink. In this case an AL80 
would be a far better choice. In Australia, most people use Fabers 232 bar 
cylinders (tanks are for army men) and AFAIK 180bar steelies would be 
illegal unless you paid to have them approved.

I own two 10.5L 232 bar Fabers (85cuft). I have never found getting fills to 
232 bar (or even higher) much of a problem and even filled to 200 bar they 
carry more than enough gas for the diving I do. With my 5 mil semi-dry, I 
wear 15lbs when diving a single AND freediving/spearfishing (no spearing on 
scuba in NSW) � so it seems that from a buoyancy perspective they are pretty 
good i.e. pretty neutral! When twinned, I wear 3lbs in the same wetsuit and 
can swim up from 50M (most of my diving) without the wing inflated or 
dropping any weight and without much effort�

So the problem with diving in a wetsuit and steels in this case is? (genuine 
question)

Also, if I were to dive AL80s I�d have to add more weight, usually seems to 
be 3lbs. As, DIR appears to encourage not having droppable weight, how does 
this benefit me in the event of a wing failure? (again a genuine question)

To be honest I think, for what it is worth, that the blanket use alis with a 
wetsuit rule has the potential to discourage people from learning about the 
concept of buoyancy (not to be confused with the skill buoyancy) properly. 
Although as a rule, it is without a doubt safe. BTW... I�m not talking about 
stages here. Alis are definitely the way to go with stages.

Year round drysuit � nothing wrong with that as long as you are not dumb 
enough to overheat.

Redundant wings � they work, but DIR says "No! they�ll kill you". I very 
much doubt that, but at the same time there is a better way (i.e. drysuit), 
so why bother in the first place?

Oh, and Gene, you have obviously learned a lot after 65 dives, keep up the 
rhetoric!

Cheers,

Si.
