I have yet to draw an Elk license but my buddy from Wyoming uses a Mathews Legacy set at 68 pounds and shoots uncut goldtip shafts, feathers with as much helical as he can get, a fall away rest, and three blade 125 grain Thunder heads. He is 6' 5" tall and has a really long draw. Uses this same set up for Mule Deer and Antelope and has taken several of all species with it.
Good luck on your hunt. I' m jealous! Maybe I' ll draw next year.
