That's true. I hadn't considered that since I'm a big advocate of brass nipples. My XR-200 wheels weigh in at 1375 grams, and dropping it down to 1350 (less than 2% savings) at the cost of durability wasn't something I was interested in.

Also true, but if you can exchange them for free instead of paying another 20 cents per spoke...

My suggestion was assuming that was already done. It still doesn't always come out just right. It's rare, but even with me measuring every rim and running 3 different calculators just to check for errors or inconsistencies, about one of every hundred wheels comes up wrong (assuming all unique builds, of course).

My XR-200 rims were similar. I don't recall the measurement off the top of my head, but I believe they were both a little larger than advertised, although fairly round. Even with me taking those measurements, the spokes came up about 2mm too short.
