The biggest factor for wheel durability is how well the wheels are built. Next is your weight and, local road conditions. Rim weight is actually fairly far down the list. I've had good luck with well built CTL370 and other lightweight rims, despite being a relatively heavy rider, provided I'm careful on rough roads. Running maximum width tyres and slightly lower pressures will help with the latter.
