I ride on hoods and drops just fine on both my Brooks B67 saddles, but I will be the first to admit I am not, eh-hem, "well endowed" in the soft tissue department. Softening the tissue-bearing portion of the leather with my hands as the sit-bone bearing portion softened took care of any issues. I'm lucky, I guess.
I am, however, well endowed in the ischial tuberosity span, and the B67 (same dimensions as the B66, B68, and B72) is truly the most comfortable saddle I've ever used. (past the age of puberty)
Height doesn't really have a whole lot to do with ischial tuberosity span. Tall women can have narrow spans, short women can have wide spans. Best bet is to let go of all preconceived notions and just measure 'em.

Edit: BTW, my outside-to-outside sit bone measurement is 170mm-180mm depending on how aero I am. You can imagine how hard it has been for me to find a lightly padded/unpadded saddle with a minimum of 2cm of wiggle room! (190-200mm) (the B66-67-68-72 is 210mm wide, oh joy!)
