Posting links to the 7.1 FX and the Coda and/or pictures of each will likely get you more responses. IMO both bikes are similarly equipped, so it comes down to money and feel; feel being more important. Ride both bikes if possible and choose the one that feels best. Saving $100 isn't worth s**t if the bike doesn't feel right. FWIW I like the Coda better - chromoly frame and fork vs. the Trek's aluminum frame and hi-ten fork, but that's only on paper. Riding them is the true test.
