I like where you are going with this. Can we try it without the "F" in the logo? Some other variations of the red star with the v that you have there might be good as well.
Your design (#13) is quickly becoming the favorite of many staff. It is better without the "F" in it. The two comments I have heard most are: 1. The "V" is a little plain--maybe a bit too narrow. 2. The font in the company name is not very interesting.
Thanks for all of your hard work on this. It really is excellent.
