    I've got a similar outlook but I have a QC6 in between the BOV and the off board, plenty flow and easy to disconnect.

    The only time iv had a problem at the surface, / pushed off the breather ,

    I had a bit of a target fixation, tide was running and i wanted to hit the shot and get down , jumped in a bit to close and smacked my loop hose on the buoy dvs parted from the mouth grip , bummer , lucky for me i could grab the shot line, stop my self from sinking as id gone in hard and heavy to get down fast , , used my 50% cylinder reg to breath , saved the grip by sticking a finger in it , , tossed loop over my head , add some /gas in wing and waited for boat to come round and pick me up ,
    new cable ties and went back in ,

    a bov would of been of no help to me ,other than maybe closing down the loop a bit faster breathing low po2 resting or Scratching my arse. is not for me

    if id not had the shot line to hold id have been going down as i deployed the 50% ,

    iv a few ways to get round this now , as i wanted it to be some what slicker if i had a same sort of problem at or near the surface, when jumping in ie start of dive ,

    even my suit feed has a nitrox mix in it , i have off board o2 so just stuck a pop off reg on the whip .
    you could plum something in to you auto air (if you have one)ie suit gas not argon lol
    or stick a reg on it , i norm have 2l or 3l off board gas x 2 , and i can get at all the gas i hump one way or the other , i can plum two whip up and join cylinder,s plug in to my buddys gas , lot,s of ways to fook my day up, lol End of day i can blow all gas in unit or breath all gas oc mode , low flow fitting so only good in shallow water oc wise ie 30m and up,

    i like to fix a problem so that it give me a 2nd benefit rather than another problem some other place on the dive ,

    a bov may sort one big problem but it makes you a good few more problems , so needs thinking about ,

    Some will say why the fook bother with a nitrox mix in your suit feed ,
    i say 45mins on a high po2 may save the day , not saying it will but no harm in trying ,
