Sorry for not giving better description as I have never had a spoke fail anywhere but at the J bend. This particular wheel set has over 10 years use on some pretty rough roads with a heavy guy on top of them. I really am mot complaining but when I measured the spoke diameters I noted the difference. They are closer to 14ga than 15ga and it is really a minuscule in difference.

In the future I am considering the Sapim Strong spokes. 13ga at the neck and 14ga on the length and just a little cheaper than the Swiss DT Alpine III
