Wanted to smoke a london broil this sunday (trying to change diet and eat a little healthy). Smoked it at 225 for about two hours and pulled it at 150 (wanted to pull it at 140 but my wife wanted it more well done BIG MISTAKE). Used apple and hickory wood and injected it with worchestor sauce. Got nice smoke ring, but next time i will pull at 140 it was very flavorful but little little dry for my taste.
