I know there's info out there... I'm lazy, that's all

and I rather have the opinion of someone who had actually used stage III cams in his/her daily driven focus than just hear "it is not recommended". I want to know why would it be a pain in the ass to use them in a dd car; because of the idle? low end lack of power? Also, I plan to use aftermarket pistons with valve reliefs so that wouldn't be a problem.
