When using my dovo shavette, I am having trouble getting a perfect BBS shave on my neck... my hair seems to grow across so the only way to do full ATG is cutting completely horizontal across my neck, which seems relatively dangerous... even with a WTG, an XTG pass and even a diagonal XTG pass, I still couldn't get a perfect BBS shave... Any advice on how to go about this? Is it even possible to get a full BBS shave on the neck?
