I have just about decided to use a 200 bar H-valve with my single stages. Of course, I will have a vintage single hose on the H.
FYI, the H-valve has to be 200 bar on the mount for the single stage if you want to get a short yoke onto it. My Mistral, DW Airstream, and Voit Polaris all will fit on a Thermo 200 bar post, but it is tight.
When you get to the resort, just ask to drain a tank and put your valve on "your" tank.
