I have 360 cc's of saline over the muscle due to a thick chest muscle from working out. I hate the way they feel. I know I would feel the implant less if they were under the muscle but I had them like that at first and because of my thick chest muscle they moved around a lot, and I hated that even more. I'm switching to 520 cc silicone Inspira (overfilled) implants over the muscle. I am hoping that these will feel softer and more natural than my current saline implants. Thoughts??
