Yay for Tricross-love threads. Interesting to hear from some owners of the Comp rather than Sport models.
Re: 3 bottle cage mounts, I really like that. I have 3 cages mounted, but find the bottom one catches on obstacles if it doesn't have a bottle in it, so I bend it out of the way. I only use it on long rides (50k+), and really just as a way of transporting water - trying to reach it while riding sounds dangerous.
Re: handlebar real estate, definitely an issue, but fortunately I'm not a gadget junkie. The Topeak handlebar bag comes with a kind of false handlebar that mounts on top, so if/when I get a speedo, I'll put it up there.
Re: cyclocross levers, I like them, overall. They make good parking brakes when at lights, and they're very useful for steep mtb-style descents - much better for keeping your weight back.
It does make it hard to justify a second bike though: it's a good enough road bike, a good enough tourer, a great commuter, good enough for anything except really rough off road, really.
