J, I agree whole heartedly with your view on single outlet manifolds. There is no redundancy, no backup. I want to thank you for an intelligent discussion of the long hose. I have worn one and had it snag on a protruding piece of wreckage and base my decision on that. I try to keep clutter and equipment to the bear minimum. Speaking as you did will make someone as pig headed as me take a second look and rethink a long hoses use. I have not been trying to say a long hose is useless, but I haven't felt it is a necessary piece of MY equipment. In fact, where snags are not encountered (ie, caves, reefs, etc.) I would recommend a long hose. If you want to see my point of view, put on your gear and crawl underneath an old pickup, with the muffler hanging and all kinds of shit in the way. You'll be scraping your tanks and your belly most of the way, even get stuck a few times. You will have to twist at times to proceed and backup more than once. Long hose behind your head is no good there, on the side of your tanks it's going to get hung up too. If anyone can suggest an alternative I am all ears. I'll think about it myself. And obviously I don't recommend for people to start crawling into every hole on a wreck. I do, though, and I rig my gear accordingly.
