Except for a brief foray into scripted sermons a year or so ago, I generally preach either from a breif outline or with no notes at all, though I always produce a detailed outline (and, in some case, a full manuscript for hearing impaired persons in the congregation).

I couldn’t agree more that this “no notes” method forces you to craft a sermon with logical flow that can stick in your brain. If I can’t remember a transition, I know it’s because it doesn’t work and it’s back to the drawing board.
