Leon,
There's really neat systems available nowadays, which not only give you light readings to 1/10th (if not more) of a stop, but, will also fire multiple flashes for you remotely so that you can take a reading at your subject and adjust your camera to suit.
With being able to take a shot and preview it on the LCD before turfing/keeping the image, unless you're really pressed for time, or have a complex lighting setup, you're right, the camera in spot metering mode should be plenty. We can push RAW files quite well nowadays, so that's more latitude right there.
