I know it's all pros and cons, but one minor con with out-in is the heat of the inhaled gas by the diver. Deep and in warm water, you could end up breathing gas that's only been cooled by the water surrounding the inhale hose and DSV/BOV. That could result in quite hot air being breathed in. Sounds nice, but actually isn't. I've never used a radial scrubber, much less an out-in, so could be talking bollocks. Worth trying though?
I have been in very warm water (80f) and was working hard.. The gas was so hot I almost bailed to OC.. So I agree in some case, temp drop is needed.. at this temp on a radia scrubber direction would have had little bearing at all.. as the gas was much hotter than it had to be.. The flow direction has its greatest effect at low temperatures.. it really becomes insignificant at elevated temps..
