If i take a picture using flash, of a grey card in one location to set custom white balance on my 40D, will that white balance be valid for whenever I use my flash, assume on camera in all situations since it will normally be the dominant light source?

Last sentence probalby does not make sense. I meant to say "assume that the camera will be used on camera in all situations". My thinking says it should be good because the flash in the situations I am thinking about, will be the dominant light source.

If you bounce the flash, the light will be the color of the wall or ceiling. An ExpoDisc with the camera pointed at the bouncing surface would work, or a grey card in the scene.

Did you delete the last sentence? I only see one sentence. Sorry.
