Thanks Bob really useful info... I had been searching rebreather valve manufacturers for literally weeks trying to find something suitable that wasn't 300 BAR DIN!
Seems WMD has a couple of rebreather oriented modular manifolds available in 225 BAR DIN/YOKE
Seems SK-0623M-225BAR could be inverted so the knob is at the top to clear the DH cans, which would give a configuration similar to vintage modular setups where both tanks feed a common manifold with a single on/off valve.
On SK-0622M-225BAR each tank can be isolated more in tune with current 'Benjamin crossover manifold' configurations.
Given I will NOT be cave diving nor using a dry suit, which setup would most suit modern DH diving?
I'm leaning more towards 0623M if it can be flipped as it appears more low profile and streamlined... but 0622M would allow more clearance for DH cans and around the wing.
Appreciate any VDH community thoughts
