Ok, stupid question time. I hope DA Aquamaster reads this. Anyway, I just scored an old Kirby Morgan Superflow metal adjustable second stage scuba regulator and I spent the afternoon and evening two weeks ago Saturday rebuilding it. It is my impression that the regulator is pretty simple to adjust after putting it back together because it either free flows if the valve arm is depressed by the diaphragm, or it doesn't. What gets me is the work of breathing required by this thing compaired to my Sherwood Blizzard, my new Kirby Morgan Superflow 350 plastic second stage regulators or even my Superlight 17K (it has a metal Superflow 350 demand reglator on it).
Has anyone every dive the old metal second stage KM/Conshelf and noticed it being harder to breath than more modern regulators a shallow depths?
