Jarhead,
The long hose doesn't change in length in relation to a diver's height. The reason is that a long hose can still be effectively routed on a short diver, but a short hose may not give enough length in a restriction. As you said you don't cave dive, I would reccomend just going with the five foot hose. This is plenty for open water as you shouldn't be going through any restrictions where the extra two feet would be necessary, but will give ample room for a low on air/air sharing swim to an ascent line or other safe place where both divers can surface on their own air. In an OOA emergency, the extra length will eliminate the stress added by two divers in unnatural positions caused by a standard length hose.
IRT Wendy's post, that's probably in the DIR gear giude section. Maybe "Evolution of DIR Principles." I haven't checked this out though. Hope all this helps.
