Hm, so I had the guy at a local bike shop hand-build me a new rear wheel when I realized I had several broken spokes.
It's been perfectly true and trouble free ever since. It's even in a configuration that Peter White offers... (I think the main part of his rant was "Don't be over 200 lbs and ask for a lightweight rim that takes 23s" but I've never talked to the guy, just read his site)
