Also know as an inside round. I want to cook one in the smoker tomorrow, and I have never cooked that large a piece of meat before. I am getting conflicting information online. This one is 11.75 lbs, I plan on using a temp of about 230F, how long is this likely to take to get the internal temp to 145. Some say 1.5 hrs per lb, which would be about 18 hours, if that is the case should I wrap it at the start to keep moisture in?
