Saddle assistance please

Been on 143 Romins and Romin Evos for the last few years with the saddle always being about 85-90% of the way there in terms of comfort. On a whim I decided to try out the Fabric Scoop Pro Flat and was really blown away by the difference I felt minus one small thing being the cutout when in the drops. I really need this, but I loved the shell flex and overall shape and broad, flat back. Anybody have a saddle recommendation/experience with saddles that perhaps hits the Flat, Flexy, Cut-out specs? Price isn't any issue. And for the sake of listing saddles I have been on and said no to:

Toupe: nose too broad against thighs. Power: wings dug into my hams in the drops Arione: felt too narrow in the back Antares: loved minus lack of cutout, but hated the VS/VSX models SMP: great minus lack of position options SSM Concor lite: loved shape, a tad too narrow in the back

I have been looking into the Astute line as well as the new Pro Stealth (looks like the power saddle but flatter and more rounded wing edges.) Any incite is appreciated!
