I like to TRex a steak on a BGE. Basically, get it very hot 750+ degrees, sear a thick steak for a minute or so on each side, take it off, let it rest for about 20 minutes, and bring the temp back down to around 400 degrees, then put it back on for 5 or so minutes for each side to let it finish cooking. Oh, that's some good eating. I also cook whole deer backstrap (usually cut into 2 pieces) this way and it is very good and tender and juicy. It is as good as any Ruth's Chris steak I've eaten. If I'm not cooking deer, I prefer a fillet or sirloin. I've never been a big fan of ribeyes.
