I've got Open Pros that have been trouble-free with more than 20,000 miles of use and newer ones that cracked will just a few thousand miles. I had some Velocity Dyad 36H rims built for touring and they are much lighter and less expensive than Mavic 719s and reportedly just as durable. My LBS also built me some 32H DT Swiss 465s that my mechanic feels are more durable than 36H OPs.
