Need Help Asap Figuring out if I Need 210 Cc Low Profile or 240 Cc Low Profile? (photo)

I currently am a B cup with sag. I have surgery next week and am deciding between 210cc low profile silicone and 240 low. I really don't want to be too big, I just want to have much more volume in my upper pole. Since my breast width is 12.2, would the 210's that are 11.2 be enough to create volume or do I need 240 that are 11.7? Implants will be combined with a lollipop lift. I'm active, want to rock climb BUT I also want to look good in a bikini. Will 210cc fill my upper pole? I'm 5'3, 109 lb
