What is the best size FireBlack lid gasket for the Bull, Stampede, and Trailblazer? I have noticed folks using anywhere from 1/2 to 1 inch wide and 1/8 to 1/4 inch thick. I know some of y'all and Rec Tec say not to use it but I am going too anyway. I am a newbie but to me I think 1/2 x 1/8 is a good size. Thanks for your thoughts.
