Green -- #7 and
#8 are great, because the the circle/ring seems to accelerate the logo name as it passes through, especially with the color change. This effect works very well. #13 is good too, feel feels unbalanced as compared to #7 and
#8, and of course has no color change.
#11 is OK, and I like the attempt to weave in aspects of our old logo (
http://axeleragroup.com), but this design lacks the "advanced" and "innovative" feeling that I'm looking for (and that you achieved better in your previous designs). Perhaps you can use some sort of gradient 3D effect to achieve this. Here are some examples:
