We like the lettering in entry 2. The orange and gold is ok, would like to see some different color schemes with a bit less orange and/or gold. Try adding the arrows to the C consistent with those on the S. We like systems on the bottom. We like the sinc/circle logo. Not sure if we like it better over the i as in 3 or in the C as in entry 5. Also, can we see entries 3 and 9 without the accent/swoosh across the letters.
