Resident or non-resident? Looks like from your profile you are a resident so the good news is that every unit awarding moose tags will awards tags to residents. That is not the case for non-residents where often the 10% cap is not even met. Was not in 2016. That makes the odds difficult to calculate for a non-resident.
You can look at F&G website and see the odds that you would have drawn a tag in each of the bull moose units. Note that some hunts are cow moose. Of course, odds change year to year but if you look at a few more years before 2016 then will see some trends.
Next, decide if you just want to hunt moose or want a tag that most hunters fill with a bull or looking to hunt one of the biggest bulls in ID.
If only want to hunt moose then isolate 3-5 units that have had the best odds for a bull tag and pick the one most convenient to where you.
If want to hunt and have high odds fill the tag then go look at the Harvest Reports for moose at F&G. Look for hunts that had close to 100% harvest. Pick one of those units which is most convenient to where you live.
If you want to only hunt for a big moose then can look at the Harvest Reports and look at Average Antler Spread. Any unit where the average is around 40" or better has some large bulls killed since some hunters shoot yearling or young bulls where antler spread is usually under 30" so takes some big bulls to help raise the average up to 40".
Good luck on your research and with your application getting drawn.
