I came across a valve [Lola?](both 200 and 300 bar seem to be made) for (I assume) the CCR guys that is two outlets, one facing the conventional direction, and one facing inward (both left and right sides) that are independently valved. There are flexible connectors being made the connect the tanks. I'm wondering the possibility of a rigid bar being made with a center post on it (no valve, just a block)..... 200 bar with a screw out plug... That way, modern bands could be a possibility. See here: http://www.utrtekstore.it/14_rebreather ... ri_sw.html
There is a solid bar made, but no outlet.
The valves are not cheap, but still way under the $$ of the XS solid bar unit.
Input/thoughts on a connector bar with a center mount?
