The only problem I see with #1 is that it has 6 colors, I was trying to keep it at 2 or 3 max. (in screen printing alot of the times you have to pay per color) so if this ends up being the winner, I will have to get a quote on it, and make sure the price does not adjust too much. Also with #7, im not sure if they will be able to get a design to stretch top to bottom. I have sent them the design, and they should be getting back to me today.
Other than that, I'm liking 5 or 8
.... to answer someone elses questions, I am under the impression that any logo by itself (not PP over a shirt) is a back logo, where the ones that are PP over a shirt will indicate front or back by the collar
