Tried my 109 today after installing the duro kit. Very happy. Cracking effort (?) was light enough it would bubble a bit when face down until I turned the knob in a bit. Super easy breathing. If I ever go back to single hosing, most likely, it will be my $25 in parts corroded 109. I am curious, when face up, it breathed hard unless I turned the knob back out. I understand the diaphragm concept from Regulator Savvy, but are all easy breathing second stages that much affected by up or down breathing? I never noticed that on my crappy regs.
