Got a #2, smoked a butt two weeks ago. Found it to not make a lot of smoke, but constant temp is so dang easy. Added chunks after about 3 hours, but still didn't get a hard bark. But the non-worry temp control sill allow me to set up and smoke something over night, after I get more acquainted with the unit. I had a bunch of hickory split sticks, so I cut some into small chunks about the size that came with the smoker. Any reason I shouldn't use these chunks in the Smokin It tray? They have splintered edges, etc due to being split pieces, but I've got them in small pieces. I plan to smoke a 6 lb whole boneless strip roast this weekend. Any suggestions on this would be appreciated.
