No J-Hooking... However, angled shaving is one way to do it but, as Kent implied, it depends on the way your whiskers are aiming. My right side neck area grows in a confused way and is difficult. Insure you do a good wtg pass to clear off the brush. Use short strokes to mow the hair down/up. Don't be afraid to grip the razor differently to get the best approach. I usually have the handle straight out on my neck when doing atg. Experiment a little.
I love a short blade for my neck - makes it much easier for me. YMMV
