Okay so I tried the the black shirt version and it doesn't look bad. I tried the font on the back with red and white but for some reason, the site doesn't want to pick up the white fully, so it just leaves an outline which looks pretty cool actually.

I still prefer the red over the white though. If I could brighten the white around the letters up and get rid of the box that's around it, it'd look pretty legit I think.
