The breast system is all you need. You can get the foam rings if you want more comfort. Some like it, some don't. I haven't tried mine yet so no comment. I don't understand what you mean by getting the large cups. Are you asking whether you can use larges even though mediums are what you need? If your bust is too small (you didn't mention your size) for the larges, then it's likely you won't get suction and will need to order the mediums anyway.
