ingalls camber kit vs revo technica upper control arms

just wondering what some of you guys have to say about the ingalls camber kit vs the revo technica adjustable upper control arms. I am thinking about purchasing a camber kit. My only concern is that I have heard the the ingalls camber kit put the stock ball joint under stress because its on a slightly odd angle and greater chance of busting the stock ball joint. Can some of you guys clear this up who have the ingalls on their DA tegs.
