I like the 3rd submission the most so far, but I would like to see a more formal/minimalistic black font type, and possibly both "A"s as the tips of the spears.
Danoeadjie, The more I look at the "A" design in your most recent logos, I'm not loving it. I feel that it is to similar to the actual form of the letter, and because of that similarity it is distracting and more un-uniform and disjointed.
