Joe,Thanks for the video, I will try it out. Probably next week or the week after. I will post the results.I have seen and done it different ways depending on how you want to do it.
Sear or reverse sear you will need a way to set up for indirect cook. On the Q that means elevating it on a rack with either aluminum foil with perforations here in the US or the nice Weber one they sell in Australia. I would check YouTube. That is how I learned to cook on the Q. Here is a BabyBack Maniac cooking a Tri Tip on a Q video.
