Timing Chain Replacement

Hey guys, I am now doing the Timing Chain replacement as I have started to have rattles on my cold start and have read it is the common issue for this problem. I'm at 65k miles. My mechanic recommends I do the phasers and sprockets with this as well, but I haven't seen any of you guys post about replacing these items yet. Any opinions?

Is the sprocket showing signs of wear? If so, I'd replace. Once they get it apart you might be better suited to answer the question of what else to fix. I just replaced the timing chain tensioners at ~50k and even those were not worn at all in the old style. My chain was fine.
I haven't heard of many people actually replacing the chain itself especially at 65k miles. You'd have to seriously have something out of tolerance to cause a stretch.

Mine were done at 77k miles by a Jag specializing indy. He replaced chains, tensioners, guides AND phasers. I have the parts, and the parts were all bad. He said that it is not atypical for engines that have had oil changes at Jag specified 15k miles. He also said it is very UN-common for cars that have had more frequent oil changes, ie, 7.5k. I saw the parts and can validate that they WERE worn.
