there all good-hay-your elk hunting right. I would really do the research with the DOW and locals if you have connections. I have been all over Colorado, it took me a few years to figure out you cant believe everything you hear-you need to dig really deep,then put your boots on. Public spots- go deep- , then dodge the drop camps, private spots, dig deep in your pocket, easy spots, forget it-someone is already on it. I would look for the most rugged area
I usually refrain from getting involved in these conversations, but thought I'd weigh-in in an effort to help you get some more feedback (like Felix said, I don't think you'll get much based on how you've asked).
I'm assuming you're asking for OTC, not OCT units. First thing to know is that "Good OTC" units are pretty much the holy grail of hunting. Because they are OTC, anyone can hunt them and they usually get hit pretty hard, which makes those good units that much more special. Very few people are going to be willing to give up a good thing when it comes to OTC units, and rightfully so. A limited tag or a once-in-a-lifetime tags is a different story. In someways it's counter-intuitive (how is it so much easier to get feedback on a great tag than a common OTC tag), but not if you stop to think about it.
There is also an element of reaping what you sow. If you are a helpful poster offering up lots of insight and advice and are pretty free with sharing your information and perspective, you can expect people to be a little more helpful. You may be a longtime lurker, but someone who's been a member for less than six months, with this being his third post, is likely not going to get much back from the community. Maybe it's cruel, maybe it's unfair, but that's the reality of things.
Lastly, it helps tremendously if you do at least a little bit of groundwork to help provide a little more steer on the kind of feedback you're looking for. For example, what do you mean by good?? That could mean a unit where you might get luck and kill a trophy, a unit where there are lots of elk, or a unit where you won't have much competition -- all different measures of "good" but rarely will you find a unit that has it all (especially OTC). Beyond that, there is LOADS of information out there on OTC units in Colorado. Do a bit of research and narrow it down a little. Do that, and if you come back with specific questions (that aren't blatantly asking for someones honey hole) you will likely get feedback that will help you out in deciding where to go.
I've hunted OTC units in Colorado three times and they were all different and all good.
