Like the direction you're headed with your Logo 4. Any chance you could explore some other symbols for the middle? I feel like I've seen that symbol in lots of other logos, so just wondered if you had any other ideas for it? Really like the colors and tagline placement though. Looks sharp.
#36 looks really cool! There are many people involved in the final decision process (my staff), so the more you create, the better the odds of the consensus picking you.
