LS Timing Chain Tensioners

[rustomatic]

So I'm in the process of replacing the cam and valve springs (done!) in my 2011 5.3, and I find myself on the fence with replacing the stock spring-type (LS3) timing chain tensioner. When the Gen IV was new, there were lots of complaints (and evidence) about this tensioner breaking (causing lots of valvetrain failure), and the idea was to switch to the static LS2 type dampener (for lack of moving parts/brittle plastic).

I bought the LS2 tensioner, but it's a big pain to install the thing, as the oil pan has to be dropped partially to access this one bolt on the oil pump pickup tube. My C4 crossmember makes this challenging, but not impossible. If I'm wrong here, please let me know.

What are your opinions on reliability of one type of tensioner vs. the other? I'm looking for experience from the tons of people on here rockin' LS3s and the like; many of you also own late-model LS-powered vehicles and may have had some experience here. Please chime in.
