Sounds like a good plan.
I take it that you dont plan on doing a reverse sear?
If that is the plan, you could always pull it at 130 IT, tent it with foil, and let it coast to 135 or there about.
It all depends on your preferred doneness.
Cooking it 225* was going to pull it out at 130 and tent it and let it rest . Its almost done. ThanksIf I was slicing it for sandwiches then I wouldn't worry about getting a heavy bark on it. How much carryover cooking you'll get depends on how high the heat is when cooking. Personally I'd smoke it at 250* until it reaches about 125* then tent it and let it rest.
