I was wondering how many racks of ribs do you get on your ECB? Do you lay them out on the grate or use a rack? If you use a rack do you cut your slabs in half to fit the smoker? I have done ribs in my ECB before but was only able to get about 4 racks on the two grates. Then I bought one of those rib racks but had to cut the slabs in half to fit into the smoker.
