You may find you can shave atg when you have more experience and better technique. Or maybe not. I never do a full atg pass, because I will get irritation and I don't care about that minor difference in closeness.

No matter what you shave with, you'll feel hair the most when rubbing your face atg. For example, my face always feels smooth rubbing in whichever direction I shave, but atg I will feel stubble. There was a time when I called this "directional BBS," but that never caught on.
