Sure Corey, if you want a short High heat cook, that makes sense. No disagreement there. The queastion is how do we KEEP those coals hot, and the fact is that some cookers CAN maintain 350*, but some CAN'T...unless you add draft by unseating the lid or cracking the door.
I've got a couple of kettles, and too many hang-on accessories, right?
Well, the thing I've noticed is that I although my "poor man's performer" side table sits very flush, using the Slide-Aside bracket as well in conjunction with the little hang-on tool hanger is a huge "no-no". I don't notice a gap or anything, and there's not much smoke leakage, but tell you what. There evidently IS a gap, an a lot added air to the fire.
I can keep a bed of coals STOKING HOT...MUCH hotter with the lid on than if I just have the table on the side. Take the table off, and I guarantee that temps will go down even a little more with the lid on. We're talking all kinds of temps, with the bottom vent settings exactly the same....but in any case, put the lid on, and the temps will plummet, relative to the degree of air still available. (If I'm gonna grill chicken and I only want med. heat, I prefer just using the side table, and like to remove even the Slide-Aside bracket.)
