So I won an 8 Back MAA on Saturday with a crystal clear bubble, but the back is a little discolored (it is the w/warranty version). I posted the link below of the item, but am trying to determine if I send it out to AFA will it have a chance at an overall 80? I have never sent one out with a back like this so not sure if others have and what they got back. I know it is not an 85 because of the corners rounding some.

Appreciate the help fellow AFA'ers out there.
