I really like the direction you've taken these; I like the font treatments in 30 and 34. I like the circular icon on the left side, although I feel there is something with more impact...the conveys mastery, zen, excellence, precise. Although I like the look of the icon in 30, it seems too gentle and refined, my favorite is likely 34, with the color. It might be possible to work with color to give it more punch.
I'm extending the context for three days, as I've been out of pocket...a couple of thoughts:
-I do like 108's split colors and motion....gives it some additional excitement and punch. Is there a way you could turn up the volume on your design a bit...we are also looking at a couple of other slogans: Driving Excellence and Drive Excellent. Could you try a treatment or two with these slogans?
Other ideas are welcome; looking for punch, edge, fast, exciting, excellence.
