I don't know if you've seen these, but they're comparison pictures of the Brooks you're considering:

The second link, in particular, shows the differences in width and length of the women's saddles in relation to the Team Professional.

For what it's worth, when I first rode my Team Pro, the nose rubbed me the wrong way as well. After a generous Proofhide rub, it didn't bother me at all.

-- Also, regarding the positioning of the saddle. The Team Pro has much less front/back adjustment than my last saddle. I was able to just get it where I wanted it, but the other option would be a seatpost with more of a setback...or for Tri's, maybe turning the post around to get the seat more forward.
