I still don't think brining (which I've done) solves the issue that once that meat is sliced and sitting out on a platter, it starts drying out quickly...
I certainly think it's an improvement over not brining. And agree with Alton that you need a good probe and to pull it at 155, not 160, as you'll get carryover and it'll be safe if you pull at 155. And DEFINITELY not to go on time or those cheap-ass pop-up thermos... Going too high on temp is always going to kill it no matter whether you brine or not, and I think overcooked is the norm for too many kitchens...
