Well, I just looked at both websites, and I don't know either
According to the MSRPs though, it looks like the regular Coda would be more comparable to the 7.2, which is slightly less expensive, or even the 7.3, if you can find a deal. Both of those have the alpha black frames for 2010, which would be lighter than the white of the 7.1. I believe the 2009 7.2 was alpha white, but the 7.3 in 2009 was alpha black.
Of course there are other Coda models too. Which one are you considering?
For the record, I recently purchased a used 7.3 and I love it. I rode it tonight to Kenpo, to the bank, then I mounted a new light and took a test ride around the neighborhood. Any excuse to ride.
I also have a Felt x City, which is a great bike, and seems tough as a tank. I like them both, but they are very different bikes. The Trek is fast. With the Trek, you are getting basically a flat bar road bike. I really know nothing about the Jamis, but many people love them.
Hope that helps some.
