Completely wrong by what I think is most commonly used as a philosophy here. 90% of people or greater I bet are leaving the bottom gas on the BOV plugged in consistently. This gives you a bailout at all depths unless you're mix is very hypoxic and then not breathable at 20 ft even. Some courses...
I'm having a little difficult time understanding your differences between flipping a switch and going to a necklace or flipping a switch and not having to even remove the mouthpiece through a hypercapnic event.
In any case breathing off a 3l is going to get you nowhere in that event. So...
BOV line runs behind my neck, splitter can be seen in my left armpit and the hose with the QC6 in this case is coming from the 50 but in the 3 l configuration comes from off board just the same. I don't run a dill mav just a push button ADV.
I have a male QC6 plug into the bottom of a splitter The splitter sends one line to my ADV and the other line around the back of my neck to a right hand feed shrimp. This is technically on board bailout since I run a on board 50 setup. But I plug offboard into it in the same fashion and use that...
I take 15/50ish regularly top to bottom back to the top again.
Never thought about intent to switch to He free mix but I am prepared to plug in 50% where it's appropriate to do so in case need arises.
I'm posting this here, if needed delete or move.

We are PADI in the a bay Clayton area.
But tech stuff for us goes down the TDI path. I have a large pool of instructors who travel here since it's a great area to dive, and will do free lance classes.
Let me know if we can help
