I have used a blow off tube since a milk stout became infected after the airlock liquid was expelled.
Darker beers always seem to have ridiculous krausen and in this instance I wasn't there to top up the airlock liquid as I'd usually be, but blow offs are just easier and safer IMO.
I have an SS Brewtech brew bucket and have just upgraded to a domed lid with pressure transfer fitting so an airlock wouldn't fit in my ferm fridge in any case.
