I tried this same approach for this unit about 1 month ago and received very little info. The group I'm in has 4 late bull tags with very high expectations, so we started scouting early and this is what we have learned.
The info provided on the Game and Fish web site provides you a great starting place and yes the areas they identify hold trophy bulls, atleast they did prior to the archery season....!With that said I spent 2 weeks in #10 before I even seen an elk, so far we have spent 7 weekends scouting the areas in 10 and have it pretty well dialed in.
My recommendation is to hop on a quad and take those 30-40 mile rides, learn the roads and areas. Select an area that suites your style of hunting and appears to hold a huntable population of elk and spend the rest of your time prior to your hunt in that area.
Best of Luck
