Giant boobs are unwieldy, and that reduces their appeal

I love big boobs. I think big boobs are wonderful. But I have recently felt that boobs that are too big aren't really that wonderful. Take this lady, Barghest from Fate. She has breasts the thickness of jet missiles. Part of it is due to her large size, but in terms of proportion, they could have been smaller and made her look prettier? Other examples include - Centorea Shianus the centaur - Lucuoa the Dragon In the defense of the above two, they are animal women, so they won't really have any issues. The point is, how big do boobs have to be before they start to look like basketballs stuck on a lady? And practically speaking, they would be a hindrance not just for the girl carrying them, but for whoever she's attached to. Unless you like to handle giant breasts, then knock yourself out. Even Fujiko Mine, one of Japan's first big boobs belles, has had her breast size reduces over time. The photos below are taken in 1998 and 2014. Do you believe in oversized breasts being too cumbersome and not that beautiful?
