I have had my smoke hollow 44 for about 2 years now. I have never modded it out but i am starting to want to do that now. I was thinking about a needle valve. I use only 1 burner at a time and usually can control this to about 225 - 250 with no problem. i didn't know if it was worth replacing the regulator with a needle valve. Also I have noticed i have some smoke leaking form my bottom door. I have read a lot that people are using the felt from the green eggs to fix this problem. Is there another or cheaper way to fix this issue or other felt I can use that is sold at a hardware store? Any other mod recommendations that you guys have would be good to.
