an offset so small, that even with the correct spoke direction it is not enough to handle the angle they're making to that large flange hub?
That's part of it, but with a 622/700C rim, there should be plenty of spoke length to mitigate that. I've never broken a spoke on my CR-18s except from overshifting (had a bent hanger, oops) and they are 559/26" so my spokes are probably 10% shorter.
There is something else going on, either with tension or the build process.
