You may find a different surgeon will offer you larger. 110-150cc is a cup size so could potentially get about 2 cups sizes bigger with 260s..
I had 310ccs. While now they are in I have boob greed and would like to be bigger ultimately the bigger u go the more chance you have of stretch marks, rippling, and other problems . So from that score I am very happy with what I have got and hopefully will be a D and not have any issues! X
