Tierdaen,
I sense anger in your posts, which to me sounds like you have had bad dealings with people in the shaving communities? If this is so, then be more specific & maybe it will help others.
I think it would be pretty hard to "convert" , a term you used, a new shaver to drop his disposables & place a straight to his face. This is a jump that a person has to want to try.
I'm sure bungee jumping is a serious rush also, but I'll be da*ned if anybody could convert/convince me to do it.
