Man I love that color. My wrecked one is still sitting in my garage and I was ticked when I found out I couldn't get a frame in that color in any decent amount of time or get a cheaper assembled model either... now I have a white one.
I'm 6'2" and bought a 58. I was measured at what would be a 59 by Cannondale's spec and have very average proportions but I went down a size because I preferred being able to throw the bike around a little easier. A lot of it has to do with riding position too... I'm a bit bigger (210lb) but I'm pretty flexible in the spine so the slightly shorter reach was more comfortable for me. I know lots of riders that have gone up or down a size to get a different fit from what is considered "the best" to give them what they do the best on.
