I went with the Trek Madone 5.2 (56 cm) but not the women's specific design. I am 5'9" with a 34 inch inseam, and felt better on a slightly bigger bike, but I changed the stem out for an 80 mm, instead of the stock 100mm. I didn't care for the more upright feel of the Pilot and I felt squashed on any of the WSD bikes. This is my first roadbike, since I ride mainly mountain and got this for cross-training purposes. I did try several different rides and preferred the feel of full carbon fiber. Trek does an awesome job with carbon fiber, and their frames are guaranteed against defects for life. I also am happy that the Madone 5.2's and up are still manufactured in Wisconsin. I know fit is everything, that's the way it is on my mountainbikes, so that's going to be your final deciding factor based on your riding style.
