Thanks to everyone for all the info thus far. My main reason for cl at bottom is for water drainage. I also figured that the wob would be fine in a horizontal plane, because the tail end would be at hip hieght or even with the body.

Has anyone tried a bail-out 'breather similar to the DDD or something with in- and exhale counterlungs, but attached the counterlungs on either side of the scrubber?

If this could work, and you have the exhale counterlung at the bottom, you can still drain water out of it, and WOB should be slightly better as the inhalation counterlung is above the scrubber...?

Unless the unit is horizontal in water, the hydrostatic pressure on the lower lung would be too great and it will force the gas into the upper inhale lung big time... not a good look... ie, won't work unless the bottom exhale lung is tiny and I mean tiny....
