I am having a difficult time in deciding which egg to buy. I like the idea of extra space with the XL, but will it still produce moist meats during smaller cook as the large? Like if you were to cook one pork butt on each, would the one on the large be more moist and juicy, or doesn't it really matter with eggs? I know on most metal smokers, if the smoker is too big, you will need to add a water pan on smaller cooks to get moist meats. Does the same rule apply to BGE's?
