80% ? 50% ? 100%?

It depends.

It depends.

Wishy washy answer (But I did notice you did not disregard the 80% )

Awww C'mon Jeff, you know it's whatever the 80% from the last fill, topped with air is.....which is usually about 40%-ish

LOL

I've never used 80%. I've only used 50% and 100%. I just like to torment you.

Uhmmmm, not likely.

The best part about steel bottles are they are REALLY negative when you need it the least

If I ever need extra (useless) weight, I'll strap an anchor to my ar$e instead.

But admittedly, that's just me.

What could be more useless than lead? The steel bottle lets you come off some of the lead and replace it with useable gas. BTW, they are all (AL and steel) pretty much negative when full. It's when you've finished the dive and you're on the way up that you really need the weight. Al bottles(most of them) will require you to carry MORE weight, not less. Steel bottle are negative EMPTY as well.

And, if you're not setting up your weights for neutral buoyancy with a mostly drained tank (like 250-500 psi) then you are going to have trouble at some point.

I'll let you take this one Steve.

come on Jeff, don't be scared....I won't bite...lol

come on Jeff, don't be scared....

Have you even used stages or deco bottles?

When diving doubles, I am negatively bouyant without any weight. Adding more weight doesn't make sense and I'm sure many others have the same problem. Plus I don't want a bottle to affect my buoyancy very much. I may have to clip or hand it off. Don't want any big swings at the wrong moment.
