It seems like the key to this is not worrying *too* much about how smooth the paint goes on but making sure that the paint is going on thick enough so that it can be easily sanded without any issues. You obviously still want to make it as smooth as possible since that makes sanding a lot easier. Am I right in thinking of it this way? That just makes the most sense to me. I'm going to try a couple of new techniques while rolling my next coat. I'll let you guys know how it goes.

PS - What kind of rollers are you guys using? I'm using little white 'roller foam' brand 4-6 inch rollers, and they leave behind a billion little bubbles (even if I use the double roller method).
