It may be heresy on this forum, however, I just sharpen the gullets. I use a dowel covered with self stick abrasive. It's easy to eyeball. Your sharpener would probably work at least as well, and maybe better. I don't grind the flat side at all.
Herman makes a good point about using the black marker. I would recommend just turning the wheel by hand when using the black marker. That's enough to indicate whether the angle is set right or not.
