I really like the 3D aspect and "forward" arrow of #6. I wondering if the red can work (I ranked #7 lower than #8 only because the blue and black are our colors, but I can see an accent color working well.
Could you work an accent color into #8? (either red or gold in the "next level leadership" box?)
We're trying to get a nice comparison between #6 and #7, we're interested in both. We feel that #6 may be a one time event logo, while #7 is more versatile.
