Just ordered a 6" 30' liner with a 25' insulation kit from chimneylinerdepot.com it was there basic liner I guess but price for everything was best I have found. Did I mess up by not going 2 ply or the flex king hd? Or is there single ply plenty and is quality? I know there has to be some here with the basic single ply so chimne in! Just found out my stove has arrived and I am picking it up tommorow now the liner ships tomm so lemme know! Thanks again
