Go with your surgeons advice hun but I would say if you have rippling with a 800cc implant it will get worse if you go bigger . Rippling is usually caused when there is not enough natural Breast tissue to cover the implant . Some people can only feel there rippling but not see it, it depends how much it bothers you. Personally I’d go smaller or the same size you already have at best, as long as like you say it dosent leave an empty space where the 800cc has been. Good luck hun xx
