Entry #5 better, but still too cartoonish. One of the dissenting opinions when we chose the name was that it sounded somehow "frat boy" and, seeing these designs, I now understand that opinion! It's not the impression we want to give, though.
I actually do like #7 the best of these style-wise and appreciate that it's a direction I hadn't thought of... it may bump up in the rankings when I get used to the idea. :-)
