That looks like a nice little setup. Whatcha gonna do with it?
My single 72s have ½" CGA and are a PITA to oxygen clean for Nitrox PP mixing. I figured I would set up a rig for Nitrox that also supported progressive equalization. The valve protector for wearing valve-down is in progress. I will let you know if this new experiment works worth spit. Besides, I needed a redundant supply system to keep the solo police off my six.
