I have not had much experience with my WSM 22.5. I have the wsm 22.5 with a cyberq (yes I cheat lol) I have cooked a few ribs (trying to get the rub, sauce, and tenderness like we like) and have cooked a few butts. I've done butts about 8 to 9 lbs and it takes about 16 hours at 225 I've found. So my question is: How do you add charcoal without getting the white billowing smoke? I currently do the minion method and fill the ring to the top and have stopped using water to extend time but still not getting 16 hours out of it. I now prefer the lump charcoal although it burns faster.
