No idea about the Imola.
I did test ride a 5200 and it felt much much better than my old CAAD. I may be mistaken but I believe the 5000 is made in Taiwan while the 5200 is made in Wisconsin to more exacting specifications. At any rate, Trek gives you a nice warranty and seems to be willing to work with customers that have problems, unlike Cannondale.
My bike is 1/2 CF. I don't worry about whether or not it will hold my weight, I worry about doing some thing stupid like cracking the frame by overtightening the seatpost clamp or using a lubrication that dissolves the epoxy holding the CF together. With a steel frame you just have to worry about keeping the rust away. Come to think of it, the best thing about owning my old CAAD is that you didn't have think very much about any of these things.
If you're impressed with the 5000 you should start a new post asking clydes what they think about their CF bikes.
