Spot metering. You only have to wave the camera around a scene and you get a good idea of contrast and dynamic range within it. on the GH1 spot metering, -1 1/3 / -1 2/3 EC with ND8 grad was about perfect without having to actually consciously watch what I was metering. On My OMs I ave to take a bit more care because the spot is much larger, but I never bracket with spot metering on film, there's no need as I've already metered around the whole scene and know what I'm getting.
