Jason: I get around these problems of malfunction-uncontrolled inflation by not connecting the inflator to the hose. The right side inflator is always stowed under a tire tube strap on the right tank, behind the wing. The lp hose is tied to it with cave line when I use a suit inflation system (argon tank and reg). When not using the suit inflation system, the lp hose that feeds my suit is used (disconnected from the suit and connected to the inflator if needed - no dedicated lp hose.) Since if your wing has failed, won't hold gas, you are aborting the dive and you will only be venting the suit on ascent. You probably will be only venting the wing too but as I said before using the siut for all your bouyancy is not the way to go. If this happens as soon as you reach depth, with most of your gas unused, you will be heaviest. Later in dive, after breathing some of the gas out of your tanks, I may be able to get away with using just the drysiut for bouyancy. When I dive wet, no matter what tanks used, I need a second bladder / inflator / on a different reg. Steel tanks that are nuetrally bouyant empty are essentially the same thing as aluminum tanks with a v wieght so they are nuetrally bouyant empty. I think the real advantage with aluminum tanks is that they are more corrosion resistant to salt water, and are less expensive. Any other advantage is lost on me. And using a lift bag for emergency bouyancy does not demonstrate thinking it through planning. I doubt you will be able to hit your stops right using a lift bag, not to mention avoid task saturation. And if you are using a low 02 high He mix (which is the smart gas to breathe) hitting your stops right is even more important.. The lift bag idea will get you to the surface. But basically, I have been told on good authority that if you spend more than 20 minutes past 200 ft and omitt your stops the DCI will not be survived.
