Zinn has a diferent opinion in his book:
Although 14- or 15-gauge (2.0mm or 1.8mm) double-butted spokes will probably have no more breakage than straight 14-gauge (2.0mm) spokes (because most breakage occurs at the nipple or the elbow, where butted spokes are thick), butted spokes will stretch more, allowing spoke loosening.
You can try Sapim spokes from
www.biktetoolsetc.com
They have better selection of sizes and sell them in bags of 20.
