So, I know a lot of this info is covered in different portions on different threads (several of which I've read), but for my sake and others perhaps, I would like to bring it together here.
First, some background. I'm a naturally negatively buoyant person. With 3/4 full lungs, I sink to the bottom of a pool and stay there. I always have to be moving not to sink. 5% body fat probably has something to do with this. Anyway, I dive BP/W (35-45 lb, not quite sure) and with no neoprene, I need my wing about 1/4 full to keep me neutral.
I say all this to ask if aluminum 100's would probably be a safer choice for me as I begin to select tanks. I was going to save up for some steel 100's, but the more I think about an absence of ditchable weight, the more I think I don't need my buoyancy any more negative than it already is. I like that steels are generally more durable (except for rust), lighter, and compact than aluminum, but should my buoyancy situation take precedence here?
