Being a new wet shaving convert I find myself questioning every aspect of my shave. For decades I have always gone N-S on my face and neck first. I see this in most how-to articles and instructional videos as well. However I just realized that my grain runs mostly S-N on my neck to chin line and wonder if my first pass (which is usually my only pass due to perceived irritation) should be S-N. Is my neck grain different than most or am I missing something? Thanks.
