The Frank Church is one of the most heavily impacted areas from wolf predation in regards to the State of Idaho. Go look at the estimated elk population and harvest reports on IDFG's web-site for the last 10 years. I am not saying that you wouldn't have success, but it would influence my decision making.
I have been looking at a drop camp with Bearpaw in SE Idaho for a couple of years, but I was interested in the archery season. Best of luck on whatever you decide
