Flat iron steak

this is my first time cooking flat iron steak i bought two lbs and coated with Montreal steak seasoning and placed it on the rib-o-lator until internal temp was about 125-130 and then placed on a hot grill to reverse sear. this is a great steak, it was tender and very juicy, thanks to the rol of course. the small one is my wife's. i placed it on the grill when the temp hit 130 and grilled for about 5-10min. grill temp was 300-325
