From EskimoBluDay:
From midas6t6: The steel 85s will only give you 5 cu ft more air than the aluminum 80s if both tanks are filled to their rated limit

Just to be a PITA (actually someone once corrected me on this) the AL-80 only holds 77 CF so the difference is 8 CF - not that it really makes much difference. LOL

Actually if you read the original question you would have realised we are talking about more like a 35 cu ft difference.
