As for pegging shadows: we Zonies grew up on shadow-value placement; I feel fairly confident placing shadow values. However, when shooting roll film, I use a mid-tone as well for the most part. The only real danger when using an average value is in very contrasty situations, when the shadows can end up severely underexposed. Highlights will be hot as well, but that is not an issue with most black-and-white films; color is a different matter again. When shooting black-and-white with average readings in contrasty situations, I'll usually give an extra stop exposure to hold some shadow detail and then deal with the overexposed neg at the printing stage.
