+1, I believe Bob's post is a good recipe for rim longevity.

My wife's wheels have the most miles of any of our wheels. She will have 14,000 miles on them by the end of next week. They are a great set of wheels, and have not needed truing since they were built. Universal Cycles in Portland build good wheels. We have their wheels on 3 of our bikes.

I don't see any reason to replace her rims in the near future. All 3 sets of touring wheels were built with Velocity Dyad rims.
