Kurt,

I think we are talking at cross purposes here. When using double 104s and 
a steel backplate in salt water most divers need only a few additional 
pounds to stay down with empty tanks. You can get that much from adding a 
canister light. So far, so good. But then if your wing comes apart at the 
beginning of the dive and you ditch the light you will still be about 10 
pounds negative (depending on what type of gas in the tanks and how much 
pressure). That buoyancy will be the same regardless of what size light 
canister you started with.

Now sure, any of us can swim 10 pounds up from the bottom. No problem 
there. But if you have to float or swim on the surface for a while with 
only your drysuit for lift it is going to be a little awkward. That is all 
I was trying to explain, but I guess I was not being clear.

By the way, this is yet another reason why it is a good idea to keep the 
helium content high. I know you understand this, but I think some others 
on the list have not figured it out yet.

-Nick
