I ordered a set of these after nationals and just set them up. So far I really like them. The leaf spring system DAA uses has always worked well but I think these will not get loose and be harder to break the ball joint.
I have used and broken the following:
DAA racers Little disk part always gets loose and has a wobble
DAA race masters Sheared ball joints off pouches
Guga Ribas. crack ball joint where it attached to mount and would wobble
