Good freaking question. I have similar growth on my neck. The hair grows sideways not down which means my initial N->S pass is not actually WTG but XTG. I firmly believe this is why I have never gotten perfectly smooth shaves regardless of the type of razor used. That being said, I'm still getting better results with a straight than I ever did with disposables or cartridges.

I've been wondering if a kamisori with its smaller blade might open up some additional angles to attack to sideways, and reverse angled growth.
