Recommendation for insulated chimney liner?

[john84]

So time flies I guess, I installed my F55 5-6 years ago I think. At the time I was researching swapping out my chimney liner with a insulated one, which I haven’t done yet.
I’m sure things change in 5-6 years so my question is, what’s a good quality insulated 6” chimney liner? Any ones to stay away from

What did you end up with? Surprisingly very little answers regarding this question on here.
