No weights with steel tank unsafe?

Wow, has this thread taken on a life of it's own or what?

It's been very insightful to read and keep up with, that's for sure.

I still haven't decided on steel tanks, so for now I'm continuing to dive my AL80's.

Due to all that goofy powerlifting/bodybuilding I do, I'm even more negatively buoyant than I was when I originally posted this, haha! I'm sitting at about 6' 247lbs, in fresh water no weight needed with an AL80 in a 3mm, 5mm boots and 3mm gloves. Even with 500psi in the tank I still sink like a brick.

Curse? Blessing? I dunno!

That restriction is specifically for dives during the UTD instructional program.

Steel (negative) doubles and wetsuits are bad idea due to unbalanced configuration which may prevent you from ascending in controlled fashion with failed BCD bladder in some situations. I'm pretty sure UTD doesn't promote different behavior during regular dives vs instructional dives.
