For thick steaks I start them in the oven. Place steaks on a rack cook at 275 until temp is about a 100to 110 degrees. Going for med rare. Then onto a blazing hot grill. Natural charcoal. About two to four minutes a side depending on thickness. Steak comes out perfectly and evenly cooked all the way through. A steak is not done right if only the middle third is done to your liking and the outer thirds are a step or two above your desired doneness. With the oven precook you don't overcook the outer areas of the steak as your trying to get the center up to temp.
We think in Similiar fashion, Sear in cast Iron pan, then put pan into oven till magic time. That's for indoors though.
