TGW1 - It was about 15# and was medium rare in 4 hours at 250 degrees. If I need well done slices, I have my gas grill hot and ready when slicing and throw the well done ones on there for a few minutes. Bingo - Bango everyone is now happy. If you want pink slices be sure to start checking temps early in the cooking process. I do every 20 minutes about 3 hours in, take off at about 125 F for MR as it will continue to cook a little bit as you let it set before slicing.
