I had this thread on my mind this week and after setting up my single tank rig with a 40" hose on the primary reg to teach an Open Water class, I kept it that way for diving this weekend. It was really nice to not have the long hose. I didn't even want to take the canister light on my dive this morning and just did it with my scouts. I may just keep it that way a little longer.
