If you've not been there (or very similar).....don't go. It is the biggest, steepest and most rugged country you will encounter. DO NOT underestimate the physicality. It's not just willingness; it's TOUGH!
That being said, it has been a 4-point only unit for several years. It is very possible to find more than one 4 to 6 year old deer in a hunt of a few days. The genetics are not as good as some places (of course, monsters can grow any place), but a 160 to 175 class deer is well within reason. Anything is possible and the deer have a chance to grow old, but it is not the best genetics in the state.
Take a bear tag. Take a wolf tag. Take a lion tag. There will be plenty of each of them. Be prepared for 3000 feet of elevation (or more) of 45 degree inclines (even worse) that you will do more than once a day.
Good luck.
