I’m curious how many of you truly map out your hair growth on your face and neck to precisely dial in the direction of your shaves in ALL areas.
This.My three passes part of the shave (wtg, xtg, atg) don't take into account the mapping so much. That stuff is really just north-south, east-west, and south-north.
The final phase, BBS Search and Destroy, does take into account the mapping of my grain directions, tested for quality by rubbing my hand against the grain in places to sense texture.
