BFing depends on what type of implants you get, the surgeon's technique, and where they are sited.

There is the danger, no matter how carefully they are done, that BFing may not work. Better to wait IMO until you're done with bubbas (time to save up and then get them done).

It's worth consulting with a plastic surgeon (if you're serious) because it's possible what you might really want is a lift and not necessarily an augmentation.
