Marty, all the shirt fronts look the same from here, and I am good with them. On the back, I like A, and would like the Camaros.org script from D if it had the same version of the 2nd line used in version A. If I had to choose one or the other I think it would be the Camaros.org script from D, with the 1st Gen Authority from A. 1st Gen Authority should be in a simpler font, like tahoma, IMHO tahoma is about the easiest font to read. The white text stands out bettor on the dark shirt. I would not use the red font. Design, or anything else done by committee can be very frustrating, thank you for your efforts.
