When I'm diving with a 7' hose, and I don't have my can light, I have a waist pocket I put on the belt which I route the hose under. I have two. One is an XS Scuba pocket that I can't find anymore, and the other is a Dive Rite thigh pocket. In a real cave environment the OOA guy will be swimming in front of you, so it's their height that matters from a safety perspective, not yours.
If you don't like the idea of a really long hose, you can go with a 4' hose routed underneath your arm instead. This method has gone out of style, but it is pretty effective none-the-less. I have one reg setup this way, although I do have a angle adapter on the hose to make the bend into my mouth a little more comfortable.
I would agree that everyone goes to the long hose with enough diving.
