Slack in new timing chain

I actually was just looking at threads about tensioners, and I like the idea of it because even if I get one that is tighter, over time it will stretch, and the tensioner should keep it tighter for a longer period of time. And they really aren't that expensive to put on, don't see why I wouldn't. Have any of you guys had success with tensioners?

I run tensioners with good results. Their not for everything such as a solid roller cammed engine that have a bunch of valve spring pressure, but their fine for normal street and strip action. One thing to keep in mind is when you have slack in the chain most likely the cam timing will be retarded. If I were building it I'd get a chain that fits right (I think Milodon makes chains .005" and .010" shorter) and degree the cam in and if the valve spring pressure isn't real high I'd use a tensioner.
