I had a Velocity Dyad rim that was showing signs of cracking at the nipple holes. Switched to a Mavic 719, eyeletted rim and didn't have any issues. But I also had a couple more wheel builds under my belt at that point, so it could have been the build, but given the option, I'll take eyelets over no eyelets. But I'll still do no eyelets if that's what's available.
