If it's a two passer then WTG and ATG, if I have gone a few (more than 2) days without shaving then all the passes, but my XTG on my cheeks I go from mouth to ear, I have a goatee and mustache so it helps trip the edges as well. I have and never will go XTG on my neck, just two ATG with 3 passers and 1 with a two pass shave. Like you I always have stubble I can feel very close to the skin, but you can't see; if I go BBS on my neck I get razor burn no matter what; so I just let it be.
