As I've gone through the process of completely tearing down and re-building my stolen-but-now-recovered Rambouillet, I noticed the headset felt a bit rough. This is the same Ultegra Headset the OP is talking about, I think. None of my local shops could get the cartridges, so I did the trick that Bill mentioned (swap top and bottom).
That definitely improved the situation, but it's still not as smooth as it could be. @Tim: If you don't go for those cartridges on eBay that Anton mentioned, I will probably jump on them.
