I'm not sure whether I should be happy to know that it's possible, or more frustrated because I've tried and re-tried it so many times and still never gotten it right (and then I don't see it until I'm nearly done). I thought I had the solution on the last round, but apparently not.

Any tips for dealing with the invisibility of the spoke hole offsets in the rim? It's a used rim, and of course I didn't pay attention to the way it was laced with the original symmetrical hub.
