Thanks so much for your entries!
It is a nice thought to use the tag line but in these cases I believe it is to wordy.
#1,2,3 - So far, the logos with the letters are not to my liking, but I do like the cleaner more crisp font you used in these entries. I would prefer a logo design other than letters. I am not interested in the stars and stripes concepts. I would like to see a subtle color added to the mix.
#8 - I am not sure about using the letter D as the logo. It may work, but I don't like the style of this D
Thanks for your hard work!
