Thanks for the kind words Puff.
My 2 smallest RF's were Earl and Bar-B - I didn't keep either one so I can't speak from personal experience. I don't think Bar-B has been lit since I sent it home to Smokerbuilder HQ last year - it was really just intended to be a trophy anyway.
Earl is still cooking and the fellow that got him swears by him - I'll have to ask him roughly how he feeds/adjusts him during a cook and I'll let you know.
