I don't have much beard (only in the neck , moustache... ) . I don't even have on my cheeks .
and the beard is not hard and thick , but gentle . so gentle that I shave only from SOUTH to NORTH (never shave in my life the opposite , not even once ! and never had any razor burns or...)
and I have genle skin , if it's important .

I'm 31 by the way .

so what is the best for me ?
full\quarter\half\wedge...?
