Glad to see you didn't cook it to death ! I know out in the west Costco has some real nice tri tips with a nice fat cap.
I will run it at 200-225 until it doesn't fight back. That's probably 185-190 and 18-24 hours for 30pounder. Then let it rest for 4hoursWhat temperature are you going to go with the clod ? How many hours do you think ? My brother did his first a few months ago, about 18-20 lbs for about 7 hours. He said it came out good. To me he usually goes to hot where I've heard around 180 degrees and closer to 12 hrs
