Is it worth it to drop my unending hunger with a socket for the normal arch trinket for UH?
RH is only useful on fights with adds like Hellfire Assault, Mythic gorefiend, xhulhorac etc. And depending on raid dps on how fast adds die, might be ok on fights like Kormrok, Iskar and Mannoroth. Otherwise stick with UeH. It syncs well with leg ring and BoS talents.

As Raikh said in the "Priority of getting trinkets for UH" thread in this forum, "RH is really only a good deal if you have wandering palgue at 9%+ of your damage, if you want a benchmark.". Take a browse through the thread, you'll learn a lot about which trinkets to use on which fights.
