CoyoteGuy,
First off, welcome.
I've changed my routine up a few times and have finally found the best way for me...
1. Make sure the skin is good and warm.
2. Apply HeadSlick (I mix it with Bald Guyz Shave Gel).
3. Start with the back in the center at the base of my neck and go against the grain, to the crown of my head.
4. work toward the ear on both sides, being careful right above the ear.
5. Flip it around and go front to back, starting in the center front & work towards the ears.
6. Touch up with Schick Extreme3.
I never go up & down on the side of the head with the HeadBlade. I think it'd be to easy to do a "wheelie" with the HB, causing cuts.
