How many of you parent a character to a character in Poser, and in what circumstances?

One of my big multi-character conglomerations was: with me, a scuba diver is usually made of at least 5 characters: man, breathing set, weight belt, fin, fin; plus a conformer (his wetsuit hood). 6 of them in (and therefore parented to) a RIB boat = at least 31 characters including the boat.
