I haven't properly planned out which way my hair grows on all parts of my face, but I'm getting a better idea. After one pass you can feel the stubbly bits and which way you go ATG on those bits. So for the second pass I concentrate on those bits, stretching the skin and using shorter strokes. I have four or five razors I use regularly in rotation so I'll try a few of them out to see which one removes the most stubble. Razor wars! My Micromatic Clog-Pruf or my ER 1912 with a PTFE generally win and also irritate the least, but a Nacet in my Rockwell 6C is a contender, and so is a P-30 in my ATT SE1.
