Guided or on your own? What State you plan on going to?
I have been on 2 guided Elk & many unguided-I have taken 2 Bulls on my own-nothing great but still Bulls 2x2 & a 3x4.
I have also been on just as many Mule Deer hunts & taken one nearly every time I have gone-all on my own, public ground, National Forests (Colorado). Elk seemed to be the hardest for me to come by though I have seen & missed several also.
I would have to vote for the Elk 1st. Good Luck.
