If u wanna look a D/DD, defnitly the 410 overs to get you there.
It reely depends what ur priorities are.
Think about which would be worse for you, bigger with rippling or smaller than you wanted?
This is how i chose. I do also think you will achieve a small looking D with 340 unders, look up bexy678. She has FAB 340 unders, im sure she would be happy to show you pics if u send her a pm.
Good luck X
