As a compromise, I start out on my head with a DE. Mow down most of the stubble. When I run out of 'time', I switch to the headblade and finish up. Get the best of both worlds. The headblade blade lasts longer because it's not cutting as much hair, and I'm learning to do the DE. I find I'm getting faster, and certain spots on my head are getting pretty smooth with the DE, but not everywhere. Just being cautious. Don't need a blood bath from my head and a hurried DE razor. LOL.
