Dan is a great guy and makes great stuff. I've had zbroz ,also, with good luck. There is always going to be someone, who can break stuff, and think that it shouldn't have broke. I glanced off a little 3" tree, or i should say ran over, with a stock 12 pro and stock arms. At the end of the day I seen my lower arm was bent. Never would have thought that would've happened. I wouldn't worry about dan's arms. It can happen with any of them. It does help that I'm only 40 miles from his house so if I bent something I could get it replaced faster than getting a stock arm at the dealership.
