Hi Mike,

You bring up an interesting topic and some interesting points.

I don't believe your test is accurate because during an unexpected CO2 hit by the time you realise you are experiencing a CO2 hit your motor skills might be greatly reduced. I personally believe a BOV is safer and quicker than going straight to bail out If diving a FFM I personally feel a BOV is a must not an option. Being a cold water wreck diver and a PRISM user I feel I can get a sanity breath in the right amount of time from holding the ADV dn (I am not sure if all units are capable of this, on a prism your dil feed is right under inhalation CL fitting and hose to your mouthpiece, so you can get a sanity breath by inhaling crushing lung flat and depressing adv simultanisly) the only neg to this is your buoyancy can and will become negative (if done wrong then positive). Being a wreck diver I am on or near bottom or structure or near a line. If I was an avid cave diver or wall diver I would feel stronger towards a BOV just because of the buoyancy factor.

Basically what I am saying is that a BOV can and should be used over a DSV depending on your CCR and the type of diving you do.
