A while back Brother Moose was kind enough to slide me a charcoal bowl, body, and lid for a 22.5 WSM. I ordered the other parts to get the whole thing working, and it has been working great - I love that cooker! I never ordered a heat shield though. Am I missing out on anything by not having it? It seems kinda insignificant to me, but I figured it wouldn't hurt to put the question out there.
