Thanks for your help. I'm looking forward to some good conversation here.
I use a 7.5 "ale pail" and rarely get any krausen out of the top. When I've used a 6 gallon, though, I've had a few messes and needed a blow off tube. Not because I WANT it to blow off, but just because it does. I'm of the opinion that once the krausen falls, the bitter tasting resins and fusels will cling to the side at the krausen line, or fall back into the beer as trub. I later rack off of the trub.
