The main practical problem found so far is the increase in buoyancy as gas is used from tanks. Especially if you carry big bail out tanks like me, and use them. Without the BCD carrying some gas in it to compensate, then there is a strong upward pull by the end of a dive. Thinking how to deal with that one...

I'm little by little go on 10L steel tanks. I put on them a slice of a kind of hard foam and they are neutral or just slightly positive if empty. Personally I find the solution better than bigger and heavier 11l alu tanks.
