The choice of implants can be confusing and since there are several philosophies about how to choose an implant, patients frequently get different opinions from their consultations.
Sometimes it is easiest to go back to basics. Choose the implant volume based on how large you want to be and then select the profile based on your measurements. 3D imaging is often a useful adjunct to help patients visualize their potential results.

Hello and thank you for your question. You are a great candidate
for a breast augmentation.  The size, profile, and shape of the
implant is based on your desired breast size/shape, your chest wall
measurements, and soft tissue quality.  This decision should
be based on a detailed discussion with equal input from both you
and your surgeon.  This entire surgery
can be performed with a small incision technique.  Make sure you
specifically look at before and after pictures of real patients who have
had this surgery performed by your surgeon and evaluate their results.  
Best wishes and good luck.
