Did my first T-Rex London Broil last night...boy did it come out great! Sear for 2 minutes each side at 650 then rest, bring down egg to 400 and cook for 15 minutes more. Pulled at 125, foiled and let rest for 10 minutes....wonderful. Very juicy and perfect medium rare. Looked so good I forgot to take pictures....next time. Thanks for all of the help guys.
