As far as getting info on units, a couple of evenings on the DOW site and reading the Elk Hunting University will give you a real education on hunting elk, and a lot can be applied to all CO big game hunting. AS far as statistics, unit information and herd information, all of it is free for the looking if you just take some time.
With that said, 300+ bulls can be had even in marginal success areas with OTC tags. I know, I have one, all it took was physical effort,going where no one else would go. 4WD and ATV will get you within a few miles, after that its foot or hoof time where any sane person would not go. Serious trophy elk hunters do not pass sanity tests.
