are you seeing the surgeon, he will go through everything. just know in your mind what you are looking for and say, he will give you good advise and tell you if it can be achieved. i knew what i wanted and he listened, told me what size would be possible, couldnt go to big because i was having uplift too, and we didnt finalise the final size until day of surgery, cause i then went to the largest he said was possible lol. good decision, it is confusing but too much knowledge is not too much, if that makes sense, good luck x
