So, I've been enjoying learning the process of DE shaving for a little over two months now and am certainly improving my ability to use my razor effectively. I've learned the importance of preparation in hydrating my face and stubble, building up a good slick lather, and have only nicked myself once thus far. My question here is related to the fact that I'm getting good smooth shaves most days with my more aggressive razors: slim on 7, fatboy on 6, and I just got a great shave from my Rockwell 6S on plate R4, but any lower with those adjustables or my EJ89 just don't provide a close shave. Is this related to my technique, my beard and skin, both, or some other factor I'm not considering? Thanks in advance for your thoughts.
