    My girlfirend recently did here OW course and had a blown O-ring. Looking at buying my own equipment in the near future I might invest in DIN regulators.

    Aside from all the other stuff mentioned here, one of the guys I dive with had a pressurized, turned off stage bottle with a yoke valve.

    However the pressure leaked out and when attempting to turn it on, he accidentally unscrewed the regulator.

    That was enough to convince me that having two very similar-feeling knobs with very different functions in the same area was a Bad Idea. Recently I switched all my regs to DIN, except for one that I saved for pool work and tropical vacations.

    If you get DIN regs, one simple adapter and you can use them on Yoke tanks.
    If you get Yoke regs, you can not use them on DIN tanks (unless they happen to be the 232 valves with an adapter which then adds ANOTHER O-ring....)

    There's a good description of the various valves and fittings - with pictures - here

    I like the way the DIN regulators look hooked up - nice and clean. I have yoke adapters for when I travel. There is a big allen on the DIN that you have to keep an eye on as if you twist the regulator when you loosen it.

    Just look at the structure, DIN screw in a long way O ring totally buried in the guts of the valve,
    Whereas Yoke has a thin rim of metal with embedded O ring, with a pressure screw in an indent holding it in place .Whack it !which is likely to stand the force and not get dislodge? My answer DIN. Yoke also presents a larger target to Whack.

    DIN regs cannot be removed when under pressure, Yoke's can. That said, I bought my regs in Yoke because I was diving recreationally, then purchased DIN conversions once I wanted to do Tecnical diving, and purchased one DIN to Yoke for use on recreational k-valves. This system works well for me.

    And why do you need to remove a valve under pressure?
