hi veronika,
you bring up many good points but the main issue i wanted to discuss was the feasibility of using BOTH of these techniques together (which wasn't clear).
also, i think you might of missed the point of these procedures: use in case of EMERGENCY---they may be inconvenient but would you rather BO?

removing the weight belt this is not something you should be doing on every dive BUT in case of BO risk/low oxygen situations. at this point "comfort" should be the last of your concerns. actually, this is a well known procedure you should consider adding to your repertoire through practice.

- drop weight: Wouldn't want to ditch my weight in a deep quarry if I don't have to. IMHO that's the ebst way to lose it. Apart from that, it's "Constant" weight after all?

again, only in dire circumstances would you drop the belt. personally, when in serious risk of BO i say screw the belt.

- remove mask: Wouldn't want to do this in 4°C water. Apart from that, as much as I appreciate Sebastian Murats spirit of innovation I'd like to see the concept scientifically proven before I'd incorporate it in a surface protocol.

nor would you be frequently removing the mask during a dive BUT instead only in cases of BO risk. cold face or bo? hands down i go for cold face. also the oxygen conserving effect on the body will apparently be STRONGER with cold water.
certainly you make a valid point about a new technique and i fully agree that it should undergo wider testing----HOWEVER, personally i will always do everything possible NOT TO BO when i in danger no matter how "uncomfortable" or unpleasant the technique.
additionally, you mentioned "work load", which is really what i am wondering---will it be feasible to perform BOTH of these tasks in a hypoxic state? (perhaps train yourself to do one with each hand?)
