When your buoyancy is neutral, taking a breath will make you
slightly positive, and exhaling will make you slightly negative.
Your rate of ascent should be slow enough that you can easily
stay horizontal and control your depth using your lungs like
a fish uses it's air-bladder.  Also, in the horizontal position,
it's easy to dump air from your wings using the rear dump valve
as you ascend and your buoyancy increases.

With or without a down-line, you should be able to maintain your
depth during deco very accurately using your lungs for fine
adjustments; always in the horizontal position.
