So, most of my UK diving is on twin 12's (steel).
I'm looking at a possible live-aboard trip next year with blue-o-two ( a mixed group of single-clyinder Rec divers, one or two on CCR and a handful who will likely go with twindies) and see they offer rental of manifolded Ali 12's. (Ali 80's?)
Would be looking at doing max 45m, nitrox, just after longer dives. Just wondered if anyone had dived with this set and how it compared (weight-wise) with steels?
I'd imagine they'd be rather buoyant when closer to empty?
With steel 12's I use a 3mm steel backplate and an extra 4kg weight belt.
