The Rebecca is the most comfortable bra I've ever worn but probably also the least flattering! I've got a Bravissimo Purity moulded bra and it flattens me slightly and gives me a very round shape but, to be honest, I don't really like it. It might be worth a try though.
I tried the Juna but it looked awful on me and gave me square boobs!
I think I'm giving up on moulded bras and sticking to my Bravissimo balconettes and wearing a cardigan or jacket in the cold weather!
