Ok, hey, carry an argon bottle for the 2nd bladder if it makes you happy. Now the two are equivalent. Except of course that one is labeled stroke and the other is blessed correct. I'm still struggling to see the huge difference. > suit. You dont wear the suit merely for buoyancy, but for staying warm. Warm If I don't need the warmth and you have just admitted that I don't wear it "merely" for the buoyancy, then the 2nd bladder is a much simpler solution. You just insisted that I add a drysuit and an argon bottle to dive in 80 degree water just so I can wear high capacity steel tanks. I thought the philosophy was to not take what you don't need. I might decide I need backup buoyancy. I can get that at the simple level with a backup bladder or 2nd set of wings. Adding a drysuit adds more complications beyond that, why add them when you don't need them? for cold water? Sure. go drysuit and 1 bladder, makes perfect sense. However in dives where exposure is not the issue, you are suffering from addiction to dogma. At worst you should be able to allow that either system meets the desires of some backup buoyancy when exposure is not an issue.
