OK, I figured out something that really helped me this morning. In the trouble areas (chin, mustache, etc), I focused on shaving just about 1-8 to 1/4" of face at a time, with the 1/4" of blade closest to my index finger. What a difference! With that whole big blade, it's easy to feel like it should all be used. Psychologically, I felt like it was the equivalent of 'choking up', like a baseball bat.

Anyway, it was very encouraging. It's not the greatest shave ever but I wasn't trying for that either, with only one pass on most areas.
