It's a pretty well known fact that any bow will put arrows in the same hole when fired from a machine. It's also a well known fact that this changes when the human factor is inserted. The forgiving nature of a particular bow is more dependent on overall design (riser, brace height, grip), as opposed to cam system, IMO. Some bows, by virtue of design, are a real bear to tune and shoot. Others are not. And it's not the cam, or cams, on them that makes it that way. Sure Hoyt took a huge chance with the cam .5. But they have a huge, faithful following. Hoyt also advertised the cam .5 everywhere, something Darton didn't do nearly as much. So now the road has been paved for the others to follow. Hybrids may be the next great cam system, but I don't think they'll be the death of all others.
