I had the Salvador Dali style a while back but, as you say, certain styles can take an eye out. It's funny when you wake up and both sides are pointing in the same direction. Or one day you look in the window of a shop and see your reflection and think, man! who's that damn weirdo? Scary! I've toyed with the pencil moustache too but it takes a lot of extra, careful trimming for me because my facial hair has no gaps in it- just a solid wall of hair-
Also, due to my colouring and where I live, people take me for Middle Eastern with the pencil moustache- and I'm not, so I choose to not be guilty by associaton of facial hair...
Wax? I think it needs beeswax in it, as a natural product, for the heavy control factor that stiff facial hair needs.
