What was the title of the thread?

I don't read Techdiver anymore.  I'm on GUE and DIR-GER. A lot less
nonsense from the Captain XY  types  there. 

Info from outside the group not accepted? The guy who redesigned the
Halcyon RB is a German guy, Reinhard Buchaly.

As for the idea with the reverse valve ... I can just see armies of divers
braking out the wrenches to open valves that are already open, or vice
versa. But you could probably come up with some color code schemes. Sounds
like the IANTD solution to a simple problem. Give Tom a call.
