Couple points to consider from someone who spends his life on the unit.
There are some of the better bucks killed right off the road every year. As much as it seems lazy, when the roads go right through where the deer are, it makes sense to use the roads.
The unit is nothing like it was 15 years ago, or 10 years ago, or even 5 years ago. Getting general info from folks that were there in 2008 is fine, but just because they say they seen four 200" bucks on magic ridge, don't expect to see the same.
If you go through Thompson springs, you're going to end up at the Sego gate to access the roadless. There's very little deer country huntable without crossing the tribal land right of way and into the roadless. It can be a good place to hunt, but takes a fair amount of planning and commitment, especially without stock animals. If you're going to access the majority of the unit from the south end, it would be through Hay canyon, East Canyon, or San Arroyo. From Carbon county, you'll be just as close and better roads going in the north side through Ouray on Seep Ridge, though there is a section under construction this spring that you will have to detour(supposed to be completed this summer).
Cover as much country and look at as many bucks as you can(thus the road hunters). Most bucks getting killed are in the 140"-160" range. Some guys put in the time and turn up something better. But don't expect to see a bunch of bigger bucks running around, it's just not what the unit is anymore.
Take more gas than you think you'll need, then take more than that. It's a long ways out there and you'll burn a ton of fuel, even if you don't road hunt.
Expect every canyon and ridge to be packed with people on the opener. It's just as crowded as a general hunt because most tags have a group of guys along to help.
If you find a good buck scouting, get him killed in the first couple days, or someone else will.
Remember it took a lot of years for many of the other hunters out there to draw a tag too, including the elk and bear hunters. Don't be a d*ck and accept the hunt for what it is, you'll enjoy it more.
Post pictures here when you kill, we'll all be waiting to see them.
