I shoot RAW almost exclusively, and I rarely consider white balance, other than 
to make sure there's a gray surface in frame. Using the RAW converter 
eyedropper to set white balance on a neutral gray object is the foolproof way 
to shoot digital.

When I did have to shoot jpegs for a VR panorama service, I set white balance 
prior to each shot with a gray card.
