Well today I was able to get the liner in pretty smooth. I have a dreaded 7x11 flue and I ovalized 6" down to 4x7.5". I wrapped it in 1/2" insulation and off it went. I had (2) 45 degree angles in there but it took about 15 minutes to get it through. I just want to say Thanks Again to everyone who gave me feedback and input!!
