Although I am not looking for the use of a 'brick pattern' what I like best about #6 is the creative use of that pattern. #5 does not work the font does not 'pop' and is difficult to read. I also want the 'series' to play an even more minor role in the logo. Thank you for entering and good luck.
You are correct, this is modern and easy to read, I would like to see more 'strength' in the logo. Bricks are supposed to be strong. Thank you again for your entry.
