Amen! I never in my life worried about it and never even heard much of it until the last year or so. In my Muzzy rest DVD on setting up their rest, they say to measure for cam lean with the bow at rest before setting up the rest...................I didn't pay attention to that and my bow is shooting fine.

I don't think their is any way to have cam lean unless the limb axle holes are misdrilled, bad axles, bad bushing/bearing, or "loose" tolerances. Add to that, their is no way that the cables are going to come perfectly straight off the idler wheel when using a cable guard at full draw. I've never seen one yet!
