+1, have the Mavic A719 rim with 36 spoke hubs on my commuter/utility bike. My mass is 100 kg, I'm not too careful what I ride over or thru- railroad tracks, broken up pavement, gravel roads, off a few curbs. This wheelset has been great- at 3000 km I took the bike in for a tune up and had the wheels checked, they were still true. IMHO- the quality of wheel build is an important factor. Getting a wheel that is properly tensioned and stress relieved - reduces the potential for wheel problems.
