Yesterday, I was down at my LDS and picked up a pair of new Catalina AL 53s. I brought them home and strapped them together into a set of "baby" doubles (My son carried them for me 'cause I'm not in really good shape right now). They are lighter and shorter than my double steel 72s and I think they will be fun to dive with my PRAM. I don't remember if there were aluminum tanks of that size "back in the day," though.
