I am drawn to #8 and I think it is headed in the right direction, however it is not 100% there for me yet. I would be interested to see this logo using colors other than green, perhaps referring to the pantone colors listed. Using the tagline is optional.
I like the direction, of this redesign, however I feel like it is missing a little something. I would also like to see it in a color pallet other than purple/green
