| Buoyancy of US 104/120s
Can someone let me know what the buoyancy characteristic of the US 104s and/or 120s are? Either with or without valve/bands (just say which). Or what the mass of the steel and the internal volume is, so that I can work it out.
I've dived 104s a couple of years ago and although I remember they were noticeably heavier than the 12s we use in the UK I don't know by how much. I know I was overweighted with a Pro-14 an alu backplate and no lead; however when I go back I'll have noticeably newer (and hence more buoyant) undersuit and a 9Ah canister. It would be good to know whether I should be taking a steel or an alu plate with me.
