I haven't done ribs on the EX6 yet, but I've cooked a few thousand on other smokers. My advice is worth what you pay for it, but here goes... 1) 225F is for pork shoulder and other long, low and slow cooks... Ribs like to be cooked hot. 275F-300F. 2) Spare ribs will take a good bit longer than back ribs. 3) Wrap/No Wrap? It's a preference. If you're a diligent ACV SPRAYER, you might skip it (or depending on the smoker.. Got a dedicated water pan?). I'm kinda in the middle; I usually do multiple racks, so I throw them all in a foil pan together, seal it with foil, and that works for me. Note that mine are not wrapped tight/individually, and nor do I add any butter/brown sugar/whatever, but it does the trick. It traps the moisture for a while (which is doing some magic). Don't drink too much beer and lose track of time; too long on the wrap and you'll have mush. 4) If they're tough, they ain't done. If they "fall off the bone", ya went too long. The sweet spot is when they easily pull clean off the bone when you bite. 5) Sauce/No sauce? Another preference, but I like to finish with a light glaze of sauce, but NOT goopy... I'm not trying to cover up the taste of the ribs. I make my own sauce, but when I don't have time, I do what most competition cooks do. I mix Blues Hog Original and Blues Hog Tennessee Red, 50/50. 6) All that said, do whatever suits you. You can't hurt 'em. They're already dead.
