Is this a common approach? I only have 3 SR shaves under my belt, but the most recent one I skipped the WTG and the XTG (except for the jaw line, haven't figured that out yet) and went with ATG only, and didn't notice a difference in the quality of the shave vs going with all three. While I haven't read this entire site yet (has anyone?) I'm curious if anyone else more experienced is going this route, and if not, why? What are the potential pitfalls?
