Thank you for your entry. I like the color and font in example #8, Green/yellow looking far better than Black/yellow. I find the idea of the shield interesting, but it look a bit too dominant in relation to the text.
Of the four new designs I like the #67 the best with #66 as second of the four. #65 and #64 are too monocrome to my taste. But I will still put #11 higher than the new ones.
