My chin is tricky, plus the jawline under it has some of the toughest facial hair known to man, probably!
I have to do 4 passes there (WTG, XTG in, then out, ATG) to equal what 2 passes do everywhere else. I use a very pronounced scything motion, otherwise the hair will stop the blade (leading WAAYY with the heel/toe). I try and keep pressure pretty light there, for obvious reasons. And as mentioned above, I make lots of little, short strokes.
Works for me, but I still wish I could do it in 2 passes!
