My Astral Velocity rims showed signs of wear about the spoke holes that went undetected because I didn't check my bike as frequently as I should. I did not have a catastrophic incident as a Result. I suspect I could have. But, I was atop a steep hill climb , when a spoke pulled through the spoke hole and a large crack about the opening. I called it quits and my wife came to my rescue when I decided to not ride home. It was such a large crack and the wheel so out of true, I decided it unwise to ride home.
