#38 is interesting, but something is missing. The font definitely needs a switch. Something less swervy/curvy. It gives off too much of a techy/videogamer feel. Something more classy/lasting/subtle perhaps? Also the blades coming off the logo are interesting. Can we add to the color palette to make it more dynamic? Maybe instead of navy/gray, we can try light blue/darkblue/green...The green can be something small to accent the logo.
