I am getting ready to buy a set of tanks. For now they will be used as singles but I want to turn them into doubles in the future. I want steel so that I can get some of the 16 lbs off my belt. I know that if they are doubles in the future the DIR philosophy is I need a dry suit but for now they will be singles and swimming them up will be no problem if I drop my weight belt.
My questions are what sizes are generally used for doubles, and what is pressed steel and what is the advantage or disadvantage of it vs regular steel tanks?
Thank for the input.
