I bought a Pilot 5.2 WSD this year. I absolutely love it.

I am 5'4" and long waisted, but I still have a terrible time finding a bike with a comfortable top tube length. My LBS thought they could fit me on standard Pilot, but they agreed the WSD was a better fit.

I love the more upright riding position of the Pilot. I am properly positioned for an efficent pedal stroke and the smaller STI shifters are a godsend. I have small hands and riding with the standard size STI was painful.

My previous bike is a Sequoia Elite, which is a great bike, but it just doesn't fit like the Pilot.
