Iron Cross Logos

Well, this is it. I'm making it public that I will be creating an Anime, called Iron Cross. I will be doing the storylines, and my bff Kuroseishin (I don't wanna give her real name for obvious reason) will probably be my Animation expert. These are just a few idea's that I've had for the logo, and I'm particularly drawn to numbers 4 and 5..and been thinking of using the logo from 5, but the lettering from 4...but, if anyone can vote on which one they like the most, then I will be most grateful...and who knows, you might just become part of the story.
