Hey the Natrelle Inspira soft touch is 461 pounds more expensive (thats the one I chose) and then theres Inspira responsive round 300 pounds more I think. I dont think they charge more for 2 cup sizes, but if u are having very big implants, I think theres a charge. You can choose your surgeon of course, if you know someone, but normally the PC suggests one that suits your needs, hope that helps xx
