28, 5'8", 130 lbs. thinking 375- 400 Mod+ or HP - under muscle .. undecided!!

Okay.. so I've been on this site and researching for ages. From my teenage years I've known I've always wanted to get a 'boob job', and I didn't really think it could happen until about last year. After going back and forth in my head about the possibilities I finally had my consultation in Kelowna BC with dr. Peterson. He was great, it was a pretty short appointment and he was very straight forward. He answered all my questions before I even opened my mouth. I showed him a few pictures of what I had in my head and he suggested around 400 HP.
I'm torn between HP and mod plus. I've looked at so many reviews and sometimes I like the look of 350, sometimes 450, sometimes HP and sometimes mod plus. I know I'm the end it doesn't make a HUGE difference but I'm still torn. Like every girl who wants a breast augmentation, or any surgery, I want them to be perfect. For me. On me. You know what I'm saying..
anyways, this site has really helped me .. it's been so nice to read everyone's journey through this process. I'm so freaking excited it's all I think about!

Here are some photos from my consultation last august. I like the 400cc best, but the nurse said because I'm going under the muscle i should size up 25cc.

Some photos I showed the Doc, all of which I took from this site
