My mother is doing a balance transfer on one of her cards and said she will add my finacee and I on as AU's to the new one if we want to help our scores. It will be a high limit card, so would that out weigh the hit we might take on AOAA? Only asking because I know it should take a hit a bit, but when I added him on as an au on my 6 month old card he got a 10 point boost. I am kinda iffy on it because I don't want to take too much of a hit.
