you will notice that in any direction you shave your face should be ultra smooth in that direction and prickly opposite. So make a pass and for teh rest of the day figure out by strokign your neck what the most prickliest direction is and make a pass that way. It'll help.

For example my quicky is a WTG pass from my chin to chest direct and when stroked (after shaving) that way it feels BBS smooth, but stroking from chest to chin its almost like I didn't shave. So adding another pass that way helps a lot. Then I add a slight diagonal pass and then I'm bbs all the way.
