I've decided to only have Piedmont and Sweet Caporals in my SGC 40 set. It's comprised mostly of those two backs now anyway, but I do have a few Sovereign, Old Mill and Polar Bear.
Looking to get back the same player/pose/grade in a Pied or SC, plus a little extra for the "back downgrade" assuming that the eye appeal is comparable. If you have something you'd like to propose, send me a PM. Each link below is of the front scan of the card in my registry.
