Hi all, based on alot of good reviews of Smokinlicious I bought a box of Ash, Maple & hickory. I see they chunks are about 2"x2"X4", what I'm wondering is if these are too big for the SI2? Should they be cut down first (2x1x4, or 2x2x2)? Going to give them a try tomorrow on some spare ribs, hope there really is a difference between these and the big-box wood I've been using.
