#6 is a nice serious font that I think is in line with our market but I'd like to see a more complex version of it perhaps with some additional details. I would be interested in seeing how it would like as a portion of an emblem style logo.
#7 is my favorite so far. I'd like to see alternate versions of that one also with more details and complexity.
My favorite logo of yours is still #93. I think if you could somehow combine that design with something similar to what you did for Crossfit Chicago or Rev Out racing in your portfolio we might have something special!
