#1: Love the font and I like the color scheme. Would like to see the grey a little darker. Would prefer the abstract mark on the left side of logo. My first thought when looking at the abstract was hurricane. Would like something that is more geometric that conveys a pattern or model. The logo at
http://www.dfaus.com is one example of something that gets my attention, though it doesn't need to be a triangle necessarily. A 3D abstract might be interesting.
