26 Yo 5'6" 165lbs No Kids - Raleigh, NC

I have decided to invest in myself. I've never been particularly unhappy with my boobs. But I've never thought of them as something to be proud of. They are just sort of... there. I've had BA on my mind for a year or so. I recently got married and the subject came up. After realizing how supportive my husband was of the procedure, I gained enough confidence to look into it. I had a consultation about an hour and a half away in Raleigh, NC. My husband was able to come with. I know most women get several, but we felt so comfortable at this office and confident that Dr. Davis knew what he was doing (25 years of experience!) that I booked my surgery that day, pending my work schedule changes.
I work as a bedside nurse, 3 twelve hour shifts a week, and can schedule myself 6 days off at a time while remaining full time. Hopefully that'll be enough. I don't have paid time off and the unit is so short staffed right now that they'd probably kill me if I asked for a month off. But I've let the girls at work know when and what I'm doing and they've agreed to help me with anything too physical.
Anyway, after my consult I knew I wanted silicone over the muscle (which is supposed to be better for crosstrainers and upper body work outs, which I've started getting into. Side note- I'd like to lose ~15-20lbs and I've discovered a great routine I've been following for a couple months. Maybe I should have waited for BA after I lost the weight I wanted, but I couldn't wait!). He said he only recommended under the muscle for women with small frames and who needed the extra concealment of the implant. I'm more broad shouldered/chested (band size is 38) but my cup size is a B or small C now. Definitely not proportional. So, that's where Dr. Davis comes in ;)
The size is what I am having the hardest time figuring out. Most of the reviews on here have smaller framed women. I'd like to get myself to a full D. I'm considering 390-420 moderate profile now. My prep is tomorrow so hopefully I'll know more then. But the all important question- is that too big or too small? Not enough profile? I've attached some pics of wish boobs, me now, and vectors 3D scan pics from my consultation. Any advice/experience/words of encouragement are welcome :D

Going in, these are my wish boobs and 3D vectors scans to simulate post implant size. I hope they are labeled correctly. The size is in the lower left hand of the extra pics. I have my appointment later so we will see what they say.

I feel very confident about my implant size since going to my pre op appointment. I tried the 421 and 397 mod + profile implants in a sports bra and in a VS lounger bra (no padding or underwire). I'm loving the looks of both. Dr. Davis will go with whatever I choose and is giving me minimal input on sizing suggestions. I'll take that as a sign that I've picked something very do-able for my size. So I told him likely the 421cc. 16 days to go!!
