Quick update
Well, I made up my mind, and will be running the Crazylegs Classic in Madison on April 30th. The deciding factor came when I took a look at the route maps for the Crazylegs and the Mad City Half Marathon (which I already signed up for on May 29th) and noticed that there is a significant overlap between the two runs. Since I've never done a run in Madison, I figured it can't hurt to get a preview of the half marathon course a month early.
