Should I get galaflex for low pole support in primary subfascial breast implants? (Photos)

I have had at least 6 consultations with different surgeons. I now am between two, however one wants to use a galaflex mesh “internal bra” and the other says that’s unnecessary. I am very worried about sagging in the long run, as the lack of sagging is one of the only thinks I really like about my small breasts. I have done a ton of research; and have come out the other end more confused. Is the mesh worth the possible additional complications? With two equally qualified surgeons telling me two different things, I don’t know how to decide.
