The one thing I can't stand is saggy soft
that can't hold any shape. Was with this girl in college who had a huge rack. I took off her bra to unleash those melons only to have them sag all over the place. It was like frosty the snowman got thrown in a furnace. Not enjoyable.
My favorite combos are a small but perky set on a girl with a big butt or a large set on a skinny girl.
