@halocline I have never and will likely never advocate lefty regs for sidemount. It doesn't make any sense to me since it forces a regulator to cross under the diver in a single file exit if used on the opposite side *i.e. long hose with a left regulator with the tank on the right means it crosses. If on short hose then the long hose is on the left with a normal reg and it crosses. If it is used on the left side, then you risk the reg getting pulled out of your mouth in a restriction as well as dealing with extra jaw fatigue from the hose.
I'm not a sidemount diver so I don't really have an opinion about this, but don't many sidemount divers use a short hose with a left hand 2nd stage on the left tank?
