Cobb, You didn't answer the question. For cold water/drysuit diving more lead is required. A V-Weight does not work very well with the Argon bottle, so one needs to add weight somewhere. I have found that I need 6 lbs (for the end of the dive to be neutral) I use two canvas pockets that I slide on to the waist belt. I have made them so I *can* ditch weight if I choose to. No big deal. Ths also allows me to use the same BC for warm water/cold water, single tanks/double tanks. The pockets are also a good place to put a jon line, notes, whatever. The stainless steel backplate would be way too much in warm water (- 8lb) So I made the pockets. I can also remove these underwater (with gloves) if necessary and they do not get in the way. Yes, I could optimize with two different BCs (SS and AL), but why? This system allows flexibility without compromising any other piece of equipment. Besides, I would much rather drop a weight than my canister.

The whole point of the exercise is for you to be able to swim up to the surface, not to ditch your weights in a mad panic and head to the surface like a goddamn polaris missle. If you are tech diving in cold water with a 7mm farmer john that needs 35lbs of lead to sink then you are Doing It Wrong. You need to be in a drysuit, a wetsuit is not an option here. And if you are in a drysuit you have 2 ways of getting yourself to the surface. If you need a little extra buoyancy you drop your cannister light and your tools. And while George knows of what he speaks, he is stating common sense, not dogma. If you think a little about the situation I think you will agree.
