It's not me that lacks a clue. My neutral buoyant aluminum tanks do not require more gas in the wings when full. With my plate and neutral tanks, I'm flat neutral with no lead at all, just like I said. The change in my buoyancy due to gas use is will within my ability to adjust for by changes in breathing patterns alone. In my warm water diving, I wear no lead and, generally, carry no gas in my wing at all. As a result, I get no buoyancy shift with depth changes either. Surprise, surprise, surprise. I don't think the letters DIR appeared in the question and I'm pretty sure they didn't appear in my answer. Since you brought it up, the answer to your question is no, I don't think this is on e of the areas that DIR is wrong about. If you had bothered to read, you might have known that already.

Would you care to explain why someone who is neutrally buoyant needs any gas in their wing, let alone more? See any DIR issues here? > 3. The trim on the Catalinas is good.

Here's the first statement I made that DIR addresses. I believe DIR says no steel tanks when diving wet, or did I get that wrong too? If steel tanks are not a good idea, I assume equally neutral aluminum ones would be a poor idea too, just like I said, right? Do or DIR find something wrong with this statement? Doesn't accepting additional negative buoyancy equate to adding gas to a wing.
