Wow, I don't even know where to start. I am going to take your word that you are not just yanking our chain here, so this will be a serious reply.
As noted in some other thread, I dove Twin 120s with two slung OMS 66 steels. In a .5 mil wetsuit. I would love me 95 lbs of redundant buoyancy.
For the love of God, why? What dive would you make that you'd need nearly 400 cuft of gas? And no exposure protection.
Because if you have to spend 30 minutes waiting for the boat to pick you up sitting on the gear is easier, warmer, and safer.
Seems you might be warmer if you traded that .5 neoprene wetsuit for something adequate. Something like a DUI 30/30 comes to mind.
Warm water open ocean diving is so different from fresh, cave, or dry diving, that I am tempted to start a Warm Water Tech Divers certification agency to rid all those people of their 'useless' gear.
You might note that I live on the Florida Gulf Coast. Amazingly, we have warm salt water here. I've even been in it. I do realize that it is different than the caves. However, I did note that the laws of physics, thermodynamics, as well as human physiology carried right over.
Huge buoyancy is a safety issue in warm water, because the sooner you can get your body up out of the water the better your circulation is.
Huge buoyancy is only necessary if you insist on diving an unbalanced rig. I am interested however, in your assertion that circulation improves out of the water. This is certainly true if one takes vasco constriction into account, but I'd be willing to wager if you were protecting yourself thermally, it would become a non-issue.
And you don't dive dry, period. You wear the thinnest possible wetsuit you can. to avoid huge buoyancy changes.
I'll take note of this... Wear inadequate thermal protection to negate buoyancy changes, but wear 95# of lift to compensate for 60# negative tanks. Got it.
And you have to dive with what's available, which means that you might be slinging Steel 66's. Because islands have what they have, being islands.
No, I don't. If I deem available gear to be unsafe, I'll snorkel, or play golf. I'd rather not put my life at risk just so I can jump in the water. Clearly, some people feel differently about this.
I think it is at least of note that the other counter voice is also a warm-ish water diver.
Several of us are warm water divers.
And the thinking that might make sense in fresh water caves, just does not make sense in warm salt water.
I guess this depends on your definition of "thinking".
