I think #7 is the most promising. Can we see some more color variations? Instead of red, try light blue or light green, maybe pastel colors, or any other color you think. Lets also have it in black, but try to make sure the name is more clearly shown, maybe by opening the spaces between the letters a little bit...?
I like both 85 and 144. However, I would like to see another design for 144, where the "e"s are more discernible and clear that they are the "e" letter. Basically, the right bottom point of the curve on the letter "e" should not be touching the top part.... Lets see. Thanks!
