Hi Claire, in general the size of the implant makes no difference in rippling. Ripples are more down to your anatomy, chest wall and amount of breast tissue. The best way to reduce your chance of ripples would be to go for the Naturelle Soft Touch implant, they have 100% fill of silicon gel is the shell as opposed to the 95% CUI and Naturelle Responsive have. I had little breast tissue on my right and none on the left due to a Mastectomy and I have no visable ripples. Hope this helps xx
