Soggy:I've seen a lot of self-proclaimed solo divers that feel the need to use a long hose. Just wondering what the rationale is.
You've heard a lot from the others about configuring the same each time. I have about seven different regulators, two sets of twins, one UDS-1 System, and four singles. I dive a lot solo, and am rarely configured the same dive to dive. Many of my regs are vintage, and sometimes I dive them on a single 72 with a J-reserve. The UDS-1 is the only system set up with a long hose, and I'm not real comfortable wraping that hose around my body; this is probably from my USAF parascuba days, when I did not want anything that could pull against my neck and not break. Unreasonable as it seems, I remember dive shops demonstrating single hose regulator strength by cutting the hose half in two, and then hooking it up to a car and pulling another car with it.
So the short answer to you question is that you don't need a long hose and octopus to dive solo. You need a well-maintained regulator and a dependable system. If you dive over 30 feet depth (or under overhead obstructions such as ice, caves or wrecks), then look to redundancy.
