I started out just doing one pass WTG, I was taught you never ever go ATG. Found may way here and found out about 3 and 4 pass shaves, and decided to give it a go the next day. I ended up with some wicked razor burn on my neck, but most of that can be contributed to bad technique (it was my first week) But, three weeks into it, I've been getting DFS with 2 passes, first WTG and second ATG with maybe some XTG for touchups.
