'm 5'4", with legs proportionately small and a torso proportionately long for my size, which renders my body a bit less aerodynamic than those long, lean, sinewy types who climb hills like mountain goats—and also makes me wonder whether women's-specific makes would work for me.
I'm about the same height as you, also with proportionately shorter legs and long toso. My own experience with bike shopping and trying out WSD bikes was that none of them worked for me. So definitely give them a try, but I'd say be open to the reality that the fit may not work out.

Coincidentally, I ended up with a LeMond. A Reno for me, but I'm now regularly eyeing Zurich frames on eBay. I loved every LeMond I test rode, the Reno was just the one that fit best into my budget at the time (also I didn't want to drop loads on a road bike when I hadn't even been on one at all in fifteen years or so).

Good luck!
