Just curious, have you tried hanging a stand south of your current position just inside where that corner comes in from the west? That is a place that I would normally look and wondering what, if anything, is there.

The major things I look for on a topo, to add to your suggestions,are saddles on ridgetops (not applicable to you flatlander ) as well as large flats on the tops of ridges. These are major funnels and areas for rutting bucks in my experience.
