Looking at the picture of your bike is kind of deceiving, because of the way it's leaning on the tree. I was wondering how much drop you have. I read somewhere that having the stem up would shorten it about 10 mm. With the Roubaix being a 58 and the Look 57.4 I like the feel of the Look much better. I'm still playing with the drop as well, but I'm always playing with something on the bike anyhow. I think I dropped the bars to much now, because my back is bothering me just below the shoulder blades. I flipped the stem back up and when I feel better, I'll start taking spacers out a little at a time. I also read that you don't gain that much with the bars dropped a lot. That would be for recreational riders of course.
