Word on the streets is that Archery OTC tags are going to be thing of the past here in Colorado. I would bet the first few years of no OTC tags thee will be a bunch of 0 point draw units available. If you are not already a member of the Colorado Bowhunters Association (CBA) I suggest looking into it and becoming a member. They are the only archery specific orginization advocating for us pointy stick and string folks.
I would suggest applying for a point first choice to start building points. Now the other side of this is that there is about 1/3 to 1/2 of point, point creep every year in units requiring 3 or more points. This means a unit that took 3 ponts this year will take 4 or 5 points when you have 3 points. Eventually you can get some better quality hunts (less pressure, elk acting like elk, etc.), but you will never catch the premium units in the Northwest corner.
Do your research on the draw statistics and find units that take 0, 1, 2, or 3 points to draw. You are looking for units that were under subscribed (had more alloted tags than applicants). Most people that are building points tend to avoid these areas because they have to burn points to hunt them. You can get some pretty good hunting in these areas and they are less crowded that OTC.
Look at the secondary draw. There are a number of these low point units in there. Be aware though that the secondary draw gives 100% preference to youth under 18 years of age.
Last resort is the leftover list, this is a rodeo. There can be some great tags that show up on this list. Keep in mind that it is not a guarantee that you will get one. Leftover day shuts down the CPW application site every year. Once the initial rush is over (9:00AM to about noon), an individual can pick through the scraps pretty easily. Just know if there are tags on this list after the first day there is probably a reason (little or no access, low animal population during the season, etc.).
As said above GET OUT AND HUNT any way you can. Get the experience while building points.
