For me, the trouble spot is just underneath the jaw line. I can shave north to south or I can shave south to north, but to get really close, I need to shave from ear to chin. A standard SR blade is too long for me to do that. I guess I could get a "shorty" blade, but I have elected to use a DE safety razor for a clean up pass for those trouble spots. Although it is not quite traditional for a SR shaver, it works for me.
