I normally dive 12L faber single, with wing and aluminium STA & backplate. I've got a set of twinning blocks etc and once in a while, I twin them up - only trouble is it's been over a year since I last used it and since then I've changed a few items of kit and can't remember the difference in weight I used

To save me a lot of fartarsing around with doing two or three buoyancy checks, can anyone tell me how much weight I should add/remove from my belt when I go from single 12L to twins? I'm buggered if I can remember.

Bugger all, I would have thought, unless you have a manifold.

An empty 12 is only a about a kilo positive as I recall, so you might need to add a kilo by adding another, and the STA loss vis bands would swing in minutely the other way. However, unless you are very finely balanced I don't reckon it'll make much odds.
