I'm not sure about Colorado but since nobody is offering you any advice- I hunt an area in Wyoming that can be drawn with zero or one point depending on the year. Archery hunting at or above timberline is great the first week of September. Generally the deer start to move lower shortly after the weather starts to change. We occasionally see them up high later but it is rare. Focus on the earliest hunt you can get the time off for. Take you best optics and glass patiently. If your not willing to sit and glass for a few hours from each vantage point, this isn't the hunt for you. It usually takes time to find quality deer to make a stalk on.
One challenge I wasn't prepared for on my first time at timber line was the drastic temperature changes in early September. Sometimes swings of 50 degrees in a couple hours happen so it is hard to stay comfortable.
