Bought 2 racks of SLC ribs today. Made my own rub taking cues from recipes here. I cut the racks in half to make sure they fit in my MF vertical. I plan to do the thicker half on the top rack for the higher temp. I've done 3 test burns to get an idea of venting. Looks like the bottom rack is about 225 while the top is about 240-250. 3-2-1 is the method I plan to use. So excited.
