When I said effort, I meant you have to put some effort in. I doubt guys are going to say over the internet what units hold the better bulls, because they will be crowded with guys looking for the same info as you.
Like I said, put in some effort. Look at maps, look at record books, use google earth. If you don't live in Colorado and don't have the time/resources to actually scout it, then do the best you can with maps and google earth.
Get away from other hunters, which means look for places on maps with no roads. After you have found a place on the map, look it over on google earth.
Another thing is what season are you going to hunt? If archery I would look at some of the units with lots of high country. If 3rd season units with winter range that are by units with high country where they might migrate out of. High country usually means less hunters cause its hard to hunt. And hunters are lazy.
Find an otc unit with nasty terrain next to a limited unit, and you will probably find good bulls there.
I doubt anybody is going to give you a handout though. Find a couple units, then really study them. Do an internet/monster muleys search on those specific units. You will probably be surprised how much you can learn just by searching. Look at outfitters websites that outfit in the units you picked out and see the quality of bulls they are taking.
Somebody already gave you a region to start researching, so that should cut down your research time right there.
Good luck and put some effort into it.
