I tried something new (to me, anyway) with last night's shave that seems to have worked well. I'll try to describe it here in case it might work well for others.

My moustache and chin areas areas have the toughest whiskers. After WTG (i.e. N-S) and XTG (i.e. E-W/W-E) passes I of course still had stubble in these areas. ATG is hard for me to do even in an "easy" area (e.g. cheek) so instead of a straight-line motion I tried little circular motions. This gave the forward part of that stroke a bit of a slicing action and seemed to help me keep the blade under control, effecting a better shave in that area than before. Kind of a variation on the buffing technique. I started with a very low blade angle and adjusted based on the feel/sound of the cutting action. Be sure the skin is stretched really tight so there is noting for the blade to bite into. Do only the tiniest area at a time.
