I saw a video of exactly this on Tiktok yesterday. They looked great.I always cut steaks by removing the bone and then cutting about a 2 inch steak slicing from the fat side down through the meat side.
If you cut like 3 inch thick the same way you can then lay the steaks flat and slice into the CSR rectangles. That should get it done, but I don't go that route. Hell I prefer to just cut 2-3 giant flat slabs and smoke them like they were a rack of spare ribs but without bones. They come out soooo awesome like this!
