I believe you. It seems everyone has an excuse for doing it.
Usually an AL80 is all that is available when I rent a tank. There are a few places in Seattle (when I visit family there) that rent HP steel tanks with DIN fittings, but I haven't ever seen a 120 available for rent, only 80s and 100s.
I have a 120 from when I was living/diving in Seattle, but have can't dive locally any more, and I'm not taking it on the plane with me to Hawaii. Personally, I've never seen another diver with a 120. They are too heavy for most people, I think. An 80 usually provides more air than I need on a dive anyway.
This subject is getting off topic and I've had enough, so I'm out.
