Either both open OR, if you can reach the cylinder valves easily, you could have one closed down (with the hoses pressured) as is usually done with a deco bottle. You need to be able to open/close the valves without thinking as you should be breathing each cylinder down by 50 bar (for example) to ensure you have half your gas left if anything goes wrong.

Not sure where "part open" comes into the equation - unless you are thinking about an isolator valve on a manifold.

Mate of mine went down for the tennis and said it was diveable.

So if I'm a right knob, should it be closed or open?

Is that a bit like having a red Jag or TVR etc. those with knobs are compensating for something else!!!!

Stand up (carefully) and be proud.
Say "I'm knobless and not ashamed to say it".

Manifolds are for wimps anyway. They only have them because they cant
lift a twin without a handle. That's why all the s/h ones on ebay are bent!
