Double-wings is different than dual-bladder though, right?

I meant dual bladder.

Doubles wings are designed to float a double tank configuration which is not the same as dual or double bladder wings.

Here is a quote from Bob Cooper:

The DIR diver makes use of a simple set of wings with generally no more than 55 pounds of lift. The wings are not restrained by elastic cords and are free to wrap around the cylinders providing the buoyancy where it is need without trapping gas. This system facilitates a streamlined posture and the all-important horizontal ‘trim’.

Double Bladder wings are not DIR. They are generally in the 80lbs+ of lift variety, and are considered larger than needed, and unnecessary in DIR.

I mention the double bladder configuration only to answer the question. The answer is NOT subject to debate, and I would encourage folks who are interested in a Dual or Double bladder configuration to post in the appropriate non-DIR forum.

Because DIR divers don't use tank/exposure suit combinations that require a redundant bladder.
