Oregon Elk

I'm not asking anybody to give me their honey hole, I'm just trying to gather info. My father and I have 9 pts for Oregon Elk and I don't want to waist them. My dad is getting up there and has never killed an Elk, this will most likely be his best and last chance at an Elk. I was wondering if anybody could reccomend a Unit in Oregon, a any Elk unit or Bull only. We will walk as far as we have to and hunt as hard as we have to, so terrain is not a issue. Like All I'm looking for is the name of a unit, that way I have a place to start researching.

Thank you
