Hi Star,
All excellent questions. The implant size you have selected seems very appropriate for achieving upper pole fullness without causing a significant increase in breast cup size. In all likelihood, it will not be too big - in fact, it's as small as an implant as is made. If you're truly happy with your current cup size, it shouldn't be too small.
Saline definitely has a higher propensity toward visible rippling. Placing it under the muscle will help lessen the rippling. If you have any soft tissue cover over the upper pole of your breast, that will help camofluage the rippling as well. If you are hollow over the upper pole, you will likely see some rippling.
Hope this helps. Best of luck.
