"The issue" emptying your BC

I hope I'm not opening a can of worms here......but what about the i3 system that Aqualung has out now? It uses the 'elevator' lever for inflation and dumping. I believe that when it is depressed for dump it opens all dump valves on the bladder.

It does... and it works as advertised...

A complicated solution to a problem that doesn't actually exist. (So with the right marketing it'll sell well).

air comes out the uppermost as water runs into the lowermost. There's something at least inelegant about that.

Perhaps. The same could be said for dive computers, SPGs, or AAS. All depends on the consumer's perspective.

The bladder isn't rigid, so there shouldn't be a significant vacuum created to draw in water. I've only test driven one in a 14' pool, but I don't recall having to drain a notably different amount of water than normal.
