I think there is more to gain from turning a 70-inch feature/enterprise/investigative story into a three- or four-part series, around 15-20 inches per story. That's just me, though. I'm probably in the minority, but I prefer the idea of chapters/episodes. Think of it like a TV show, if possible. I think you can sell a larger quantity of papers that way. Less of a one-and-done mentality for rack sales.
