Great job, Gore!
As noted, I don't sear any more, and I've switched to cooking at lower temps. I've tried just about every method possible and have gotten good results from all of them, but I like the even temperature across the roast that the lower temp cook gives and I get enough color/crust on the outside without the work of the reverse sear.
One thing that hasn't been discussed yet is the prime rib method developed by Stuart, the president of Cookshack.
He originally developed it using the Cookshack electric smokers but it works even better in an FEC-100. Basically he cooks the rib roast at 250 for 12 minutes per pound and then drops the pit temp to 140 and hold the roast at 140 pit temp for at least 4 hours, preferably longer. The real key to this method is the extended hold time. I've found that it gives the juices time to distribute flavor throughout the roast and gives a great result. I've modified this to cook at 225 instead of 250 and go longer per pound, but still use the extended hold.
