im in a similar camp to stuart i use one because my unit has one and i did my training with one - but i also read the gag strap eases the stress on the jaw on a long dive- i haven't done more than a 90 min dive on my unit yet so i don't know if this is a big deal or not.
I imagine a hypercapnia episode would be a goods reason to have a BOV but how much time do you have before it gets to the point where you cant take the DPV out -surely if you recognise a build up then you have time to go OC
