Idaho does not have appoint system. you can apply for controlled hunt tags or buy a over the counter tag and hunt in the general season. you can call Idaho fish and game and speak with a biologist for each region and they can help you on which units produce the most trophy class animals. on their website you can go to the hunt planner page and look at harvest statistics for each unit during general season and/or controlled hunts as well as get a list of outfitters for the state.
