Revvy doesn't really post here anymore. He hangs out in Facebook mostly now.
Regarding blowoffs, I've had to use them. Some yeasts are very active, and if you don't have good control over temps, or you have a high-gravity beer, the krausen can build quickly.
I keep two blowoff assemblies in a plastic pitcher. I never start with a blowoff, but if I notice a problem growing then I'll use them. My assembly is simply a long piece of silicone tubing stuck into the hole of a universal bung. They look like the one in the back left of this pic. I had to quickly come up with a bunch of them... those are all wheat beers that got a little out of hand.
