Perhaps a good topic for a recreational sidemount class would be a discussion of "one tank or two", and an exercise involving single-tank diving.
For cold water, single tanks are a bit of a pain because we tend to dive steel cylinders here ... my SM tanks of choice are HP100's. I've dived a single configuration before, and although it's doable, it's not exactly comfortable. I imagine an AL80 would be a much easier choice, but then I'd be adding eight more lbs of weight to my rig, and some of that would have to go on the tank itself to maintain trim as the cylinder were breathed down. It would also require reconfiguring my regulator to probably look more like the one I use for single-tank BM diving.
