I have this exact problem also. I've developed a sweeping circular to deal with it. My valles are almost like sinkholes (using geography again) on either side of my Adam's apple. I put my razor up above them w/the scales inward on my second pass and sweep the point down carefully into a near vertical position. I reposition and do again until the area is good. This ends up as a cross between ATG and XTG, and is a little tricky, and I've cut myself a few times, but is the only thing that actually works for me. Hope that helps. Good shaving
