I like the way the K sits under the M in 7 and 8, it also starts to look like a crown which helps with remembering the kine/king (good association) of the company name. But 7 and 8 overall aren't doing it for me (and fail to show motion, transcending-ness, etc)?
The executions are very slick, but not really my thing. 2 and 5 kept my interest the most in a visual sense? Hmm.
