Back to subject, I have been experimenting a bit and have found things that work quite a bit better. My neck has been difficult as well but mostly because there are so many contours to learn. Been trying out the whole 'scythe' thing (I think that's what its called... shaving with a slight arc in my stroke instead of straight) and at a slight angle (not quite AGT, but not completely WTG either). VASTLY improved results. Now I only have to touch up back by my ears under my jaw (that little cranny is still tricky) and just teensy bits around the chin.

Little by little I'm getting better.
