I enjoy smoking ribs on the WSM on 18.5" but it just seems that there isn't enough room. many times a slab of ribs is touching the sides when trying to smoke the ribs. I've done the rib rack but still the length is an issue. I don't really want to cut my slabs in 1/2 and I don't want to roll my ribs either. Does the 22.5" fix this problem? anyone have both smokers? thoughts?
