Oooh! Thank you for pointing that bra out -- I'll bet it would also work for me. That is, if it comes in my band size. Which it probably does not. Or I'd have tried it already.
What makes me think it might potentially work? Well, I have had luck with the Feathers style (though I have to size up in the cup). But also, it looks like it has a wide space between the cups and that is good for my personal shape.
In looking at other styles, that is what you will be aiming for. One that has that little spacer between cups, or possibly a plunge style (like the Feathers). Another type of bra that can work for wider spaced breasts is the demi or balconette, depending on support needs, of course.
I don't have specific styles to recommend beyond that. Like you, I've tried some Wacoals which have been "okay" but not perfect. I have a Chantelle that I quite like, or rather, I quite liked it in one colour and not the other, which bit into me somehow.
