I think looking at a little tiny TV set on the back of your camera disrupts your flow.
When I used to shoot things that had a journalistic component I used to like to work up to an approach. By that I mean that I would shoot, adjust my position, shoot again and continue until I felt I had a variety to choose from, and a feeling that at least some of the results would have their own particular strength. Having, in my minds eye, a memory of a progression of results seemed to help.
In addition, having a variety of choices allowed for the varying needs of editors in respect to placement on a page and cropping.
Somehow the "screen" in my mind tended to be larger and clearer than the screen on the back of most digital cameras.
