Good afternoon!Having placed over a thousand Mentor Xtra implants, I can assure you that patients LOVE them. They come in 2 profiles- Moderate Plus Xtra and High Profile Xtra. They do have a little more fullness, a little more firmness, and a little more projection than their corresponding Mod Plus and HP sisters, but I would not consider them less natural- it really all depends on what you have in mind as your goal look, size, proportion, etc. Best to find a good, experienced surgeon, have them measure your chest, review photos with you, and then have you try on the implant sizers. This is really the best way to determine the best implant for your body and your taste.
