Jeff, don't misunderstand me. I'm a BIG wsm fan, no matter the size, and have been tempted by the 14 now that they even sell em at our Walmart. And to be honest with ya, while I've smoked many a slab of ribs on weber kettles, I've NEVER even tried a butt or brisket on one. I started out with a stickburner, then made drum smokers (UDS), then bit the bullet a few years back. Plenty of folks do....but then again, I'm with ya, sounds to me like the 14 is nearly the set it and forget it smoker as the 18 and 22. I don't see why you'd smoke a butt or brisket on a kettle if you got a bullet, but folks do.
As to the kettles, the way I've smoked ribs is putting a pile of lump to one side and lighting the top, adjusting the vents as needed. Some folks have a hard time with it, but then again, some folks have a hard time with the wsm. I think the lid fit is huge if you're trying to keep low temps, but I'm not trying to get you to smoke ribs or other BBQ cuts on your kettle. I was just coming from what a lot of Weber folks might say. One word though: chicken. Did you see Dwain's spatchcocked chicken in the photo gallery? Was it Sunday? Dude, there's something almost magic about how even the weber kettle cooks with coals to one side, meat to the other. Then you just crisp the chicken over the coals. A weber kettle is winner winner chicken dinner!
