I dive non-manifolded, backmounts from time to time. The cylinders are inverted so that I can do shut downs really easy. The hoses have to be longer to fit.

Protocol is just like diving sidemounts (which I do mostly). A lot of my friends will dive independent backmounts in places that are big enough for them (usually not in the UK).
