From accounts of a couple guys on a Yahoo! group I'm in, they had Peri and were not in the clearly "recommended" range. They had C cup, maybe larger, but they insisted on the procedure. One mentioned having had one revision, which is common with Per anyway, but the results from them were apparently great and they are quite happy.
So, M.Grimm, perhaps you could reconsider things with your doctor. It is your decision, it's not necessarily "set-in-stone" according to these guys accounts. It's your chest, your body, your money. You now have a choice. Good luck.
