I ended up getting neither. I went to my LBS and ended up getting a Selle SMP TRK - the men's version. I compared the men's and lady's and the differences as I could see, were the men's was longer (which doesn't bother me at all), and the women's was a tad wider in the back. 177 vs 160mm. 160 is fairly wide for a men's saddle anyway.

Took it out for a 13 mile ride yesterday, which is long for me, and it was a whole new experience. My sit bones were, for the first time, fully engaged in the sitting process! Now I'm kind of interested to know how the lady's saddle feels in comparison, but I don't feel like the men's saddle is a bad fit. Of course, now I have to get hardened off to bouncing around on a different part of my anatomy, but at least it's the correct part.

I'll be taking it out for a ride again today.
