Far to much emphasis is placed on matching your pants and jacket.I am guilty of that almost to the point of obsession,I don't think I will ever catch up with Gary/Germ though.LOL
There are all kind of straight lines in nature.If you have a great pattern that breaks your outline I see no problem with mixing them up.
Predator,ASAT,Enigma are my favorites.I have had excellent experiences with all of them almost to the point of being unfair.Almost!
