It's great to learn everything you can regarding breast augmentation, available styles/sizes/manufacturers of implants, etc. If you find you're dealing with a surgeon who thinks that anything larger than 500cc is only intended for strippers and porn stars (or similarly outdated notions), find another surgeon. Larger implants exist, and so do the surgeons who know how to implant them.

That said, don't try forcing your opinions onto a surgeon. An open discussion is one thing, but trying to convince him to do something against his own personal and professional ethics is just wrong; this is not a battle you will win. Another thing to remember is to go with your gut instinct; if the consult is going reasonably well, but something inside you is telling you this surgeon isn't for you, listen to that inner voice. By the same token, if you have a consult with a surgeon and things are just clicking for you, he is most likely The One.

A surgeon's experience will be critical here. Be aware that the creation of the implant pocket (or modification, if you already have implants and are going back for an upgrade) will be a strong determining factor regarding the final results. The implant shape (eg, HP or high profile) will have a modest influence on the final outcome, but the pocket shape will have a major influence. Poor pocket creation/placement will have poor results, no matter how amazing the implant's reputation is.

Start collecting pics of the look you like. Create a folder on your computer, save what you can when you can. Periodically go through that folder, weeding out all but your top 5-10 most favourite pics. When you go looking for pics, you'd be best off looking for pics of women who have obviously had implants, as otherwise the surgeon will take one look and know immediately that a) the woman is natural, and b) he can't achieve that look surgically. More specifically, consider women who have amazingly large and full/pendulous breasts versus women who have obvious implants. As much as any of us like the look of natural/pendulus, no surgeon can recreate the pendulous look, at least not without a significant implant volume (ref: Keisha Evans).
