Why would spokes break at the bend?
It would be mysterious if they broke anywhere else. The bend is never perfectly supported, so as the spoke stress cycles, the bend gets straightened and then springs back, eventually leading to a fatigue fracture.

Thanks tester. I guess I'm perplexed as the wheel hasn't really seen alot of use.
I do recall my spoke tension wasn't very even (per side), primarily because the Open Pro just was all over the place after initial tensioning and I guess I had to vary it somuch to get it to true.
Might persuade the rider to switch to Sputnik or archetype or something solid like that.

Just after lacing, while everything's still loose, it's worth flexing all the head-in spokes hard inwards against the flange - helps get them aligned a little better and improves the support a touch.
At least, that's what Jobst tells you to do.

All:
Was out riding yday, friend whose wheels were built by me had sudden spoke breakage. He was not particularly kind to these wheels, saw him bump the bike down kerbs at least twice in the preceding 30 miles, but not totally abusing them or anything.
Spoke broke at the bend. Build is DT Alpine III on Open Pro, Chorus 9sp hubs. I did have to file a tiny bit at the holes to get the spokes in.
We did emergency bodge re-true by the road. Will have to repair, any starting advice on how to get this wheel sorted?
