Also, even the best handbuilt wheels will have a tiny bit of spoke windup, which will make a ping as they return to a neutral position.
1. they have been pinging for months now. I've never had a good set of wheels ping for more then a block or two.
2. There should be no spoke windup at all unless he has the iro disk hub. I've never had a wheel where the windup led to constant pinging anyway and I would guess that such a wheel would break spokes all the time too.
It sounds like he got a bad wheel. He should complain and get a replacement or they should pay for his lbs to properly tension them.
