Shades of Gray

My trim painting in the dining room is now about 75% done so I figured it was time to slap up some of my gray options.  This gives me a few days to mull them over and check them out in different lights.  I have it narrowed down to 5 choices. 

I'm hoping to have my decision made by Sunday.  I'm going back and forth between two colors right now.  Here they are in chip form in the order they are painted on the wall.
