I own & use double AL80's (twin 11L/bar tanks for 22 litres/bar total) all the time for recreational diving here at home in SoCal, just because it happens to match up well with my cold water SCR (Surface Consumption Rate) of 22 litres/min*ATA.<snip>
It's not so much having dives that require them, but I have met a couple people (one of them GUE trained) who always dive doubles, primarily for redundancy but it also makes gas management a little bit easier if you do multiple dives on the same set of doubles. I don't really know how difficult it is to haul or dive with doubles or anything like that, and maybe I'll find in the future that I'll want to use single tanks unless I absolutely need doubles. Which I guess brings up an interesting question, do most people who are trained and own doubles, dive with them all the time or only when necessary?
22-divided-by-22 equals a One bar/min*ATA SPG translation, so it makes my on-the-fly gas management tracking & calculations at depth that much easier. . .
