Timing chain set

I really like the rollmaster best but I run allot of the summit chains and they are good. No matter what chain you run I strongly recommend a cloyes tensioner. We have seen allot of chains (cheap and expensive) have stretch with very low miles even though they were tight when installed.
I was thinking that originally but have read here where double rollers don't play well with the plastic tensioner blocks. They tend to tear up the block and shed into the engine.
