I feel your pain ...For years, I too searched for a saddle that would accommodate a woman's anatomy. I finally found one that was perfect for me (Selle Italia Diva Gel, without the open slot) and I loved is so much that I bought an extra one for that sad day when the cushioning gave out.
It might not be optimal to focus solely on Brooks saddles. Instead, I suggest you look for one that is wide enough for your "sit bones". Also, I suggest a saddle that is flat (both length wise and laterally). The flatness will allow your sit bones and the front of the pelvic bone to bear all the weight so that the "tender tissue" doesn't get compressed.
There is a forum for women (TeamEstrogen) that has a very extensive posting on saddles. It might have some helpful info for you.
