Did one on Saturday. Marinaded in Terriaki sauce, but that was for my wife. Removed excess fat and silver skin. I would probably have just gone with salt and pepper, or Montreal seasoning. I got the grill (I have an Akorn Kamado) very hot, above 600. Grilled for around 4 minutes per side. Rested for 10 minutes, and sliced against the grain, straight down through, maybe a quarter inch thick slices.
Easy as can be, but you need to be real careful not to over cook, or it gets very tough.
