The thicker head makes them roughly 25% stronger than straight gauge. I regularly use very lightweight rims…Velocity A23 and Mavic XC717 mountain bike rims…without constantly breaking spokes. But I use triple butted spokes exclusively.

This article explains why we should use triple butted spokes. You might even be able to use your existing wheels but going to a 36 spoke wheel would make for a more durable wheel.
