Lightest MTB hoops?

I haven’t considered a Chinese option. I’ve heard some horror story’s! I was in a pace line doing about 27mph. The dude in front of me was on Cervelo S5 with Chinese carbon bars. He hit a pot hole and the handle bars snapped sending him OTB! I’ve been a skeptic ever since.

I have a friend who rides the same rims you mentioned and has never had a problem. I might consider them.
