Well, I'm a couple hours into my first smoke with my new 18.5 WSM. I'm using one chunk of hickory and 2 chunks of cherry wood. So far I think I made a great choice in smokers. I'm just using a rub, no foil or spray etc. I might put some sauce on one rack 15-30 mins before I pull them. Instead of water in the pan, I'm using lava rocks that you would get for a gas grill. I covered them in foil to make clean up a bit easier. I got her up to temp pretty quick using the minion method. The temp stabilized around 252 on my Maverick ET733. I put it through the grommet hole sticking into the smoker about 1.5 inches. The lid temp is reading about 230. Around the start of hour 2, my alarm went off and it climbed to almost 295. Took me a couple mins to figure out that the probe had some drippings on it. I moved the ribs away from the probe and cleaned it off. Temp is reading 255 and pretty stable. I hope it taste as good as it smells.
