I'm glad that it came out great! Since you are cooking in an FEC, you should try Stuart's (the President of Cookshack) Prime Rib method.

He has two methods, one that calls for a high temp sear at the beginning of the cook. I've never bothered with that. The original instructions are also written for the Cookshack electric smokers, but I talked to Stuart at the Fast Eddy class last year and he does his in the FEC most of the time. Basically he cooks the prime rib at 250 until it is about 125 internal and then set the FEC to hold at 140 and holds the roast in the FEC at 140 for at least four hours. This really lets the juices circulate and distribute the flavor throughout the roast. The result is fantastic!
