After 8 years of trying to figure out secret to OTC bucks like you are asking about, I have concluded there are NO secret spots. Areas that are known for routinely producing 180 bucks are ALL draw areas. But....all areas that have deer have 180 bucks, but it will take a ton of work, patience, and frankly luck.
The areas you ask about seem to have had their deer numbers go down over the last 30 years, even more so than some other areas. I spoke with a rancher while on a Nov elk hunt in 51 in 07 who said the deer numbers went down over the past 25 years while elk numbers increased. Not sure he is right, but his family ranched that country for over 100 years. I sure didn't see many deer and certainly not many big bucks while on our elk hunt, and that was during the rut and they were in the hay fields.
There are a lot more deer in units like 32a, but there will be a TON of people. so pick your poison, they will both be SUPER hard to fill with a 180 tag, especially your first year. The units you ask about will likely have a lot less pressure(not none), but you may only see a deer a day. So pick your poison, deer vs pressure.
