With a short cook, 2 hours at 225, there won't be much color on the meat. I would lower the smoker temp, 180°F, and Smoke to an IT of 110. Rest 15 minutes, then Sear it on a screaming hot Grill to an IT of 130 °F. Rest 15 to 30 minutes while the IT rises to about 140. All in, 2 hours should get 'er Done...JJ
