Not true, they have a swing of ~7#'s, same as steel 100's. 100cf of gas weighs the same no matter what tank it is in. Now, what is not so good about them is that when they are empty they are 3#'s positive in the water when empty and they are 8" tanks. Steel 100's are 1.5#'s negative in the water when empty and they are 7.25" tanks. So, the only real disadvantage of the AL100's is that you will need to wear a weight belt when diving them, but at the point you are at right now you should probably just double up your AL100's and put the money you save towards a nice can light or some other piece of gear.
Really? Then why do I spend so much time, energy and money swimming into holes in the ground?
I think DA has a good point if he hooks me up with several different type setups ill be able to make the best choice on what I need to buy as far as tanks. The alum 100's I have now arent really the best in comfert but really I cant tell to much between 80 or 100's other than bottom time. On one occasion I even out dove my roommate with a 80 when he had a steel 100. Overall after getting wet a few times with different set ups I should be able to make a little better choice with what I should get.

Good luck with your training Last Mate, I have enjoyed it thus far and there is still much on the road ahead of me. Remember something, every-time you cave dive, it could be your last --- dive safely and never become too bold and complacent. The most fallible piece of equipment a cave diver has is his(her) mind, rushing through training would be like rushing through a semester long class in a month and a half --- you may pass the test, but you do not retain the information. Again good luck and wish you safe dives ahead of you. It looks as if your attitude has changed radically and I hope it stays that way.

LastMate,
Please, please, please slow down. There are some very seasoned and "positioned" posters to this thread that are thinking, albeit off the cuff, that you are a future statistic yet to happen.
Please heed.

I don't see a problem with doubling up your AL100s for a good starter set. You will be able to buy a pair of HP130s and use the same bands and manifold. AL80s make pretty good starter doubles, especially in wetsuit situations. I would assume AL100s have similar buoyancy.

The HP130's is what I was thinking about cuz worse case if I hate them I can always dive OW singles with them. But Im gonna do a few test dives with DA before doing anything.
