Washington International CollegeLogo Design Contest

Can you please remove the Washington Captiol Building? I really like all three of these but the Capitol needs removed. Is there any way you can make #3 an outline of the world and not just the U.S.? I really like how simple #5 is and might move that up to my top 3.

I have a design idea that might work that uses the world, will have to work on it in the morning. Thanks for feedback.
