I'm 172lbs racing on my steel frankenbike with my old
Campy Vento wheelset for the second season in a row. I alternate between these and 32h Open Pros with double butted spokes.
The Open Pros have needed serious truing 4 times, the Ventos never. The deeper rim probably helps. I usually bottom out at least a couple of times per race. I cringe at the sound, but they've held up fine. (I probably just jinxed myself.)
Already stated above, wide tires + low pressure absorb most of the impact.
