Mentor Smooth round high profile extra 535cc, 6ft tall, 32A/B, 12cm BW, 150lb

Had my sizer app which I feel was rushed into about 10min and told to just pick a number I felt happy with and not try about the rest.
I had gone in thinking I wanted a moderate plus profile but he's messaged to say he's going for mentor smooth round high profile extra. I guess this is because of the size of the implant and my BW only being 12.
I'm just so nervous and feeling like I'm at a point where I just don't know how they are going to look on me and I'm so close to cancelling it.
I'm booked in a few weeks time and I just don't feel like enough time was spent. I wanted a teardrop shape and had wish pics and he just wasn't interested in seeing them.
