Any “skinny” AL 100 manufacturers?

This is what you wrote and to which I was responding:

"The difference, however is that the AL 80s become positive as they are empty. Steels remain negative throughout. Though in most cases, we are only talking a pound or two."​

As I wrote, that does not matter.

That's pretty much what I said, or at least meant to, in the full post. I was responding to another poster that stated the buoyancy swing was less in the HP100, which is not correct.

The AL80s do become positive when empty. I agree, that if properly weighted, it doesn't matter. You just need to account for this in you overall weighting.
