Well with the amount of points I have accumulated I would like to get something respectable for the investment of the time not getting a first choice when I could have paid $33 for a tag instead of $500. I was saving up for a 201 hunt to get a "trophy". But to your question of what am I looking for, I know what the reality is of Colorado versus the idea many have of what a trophy is. A bull in the 320 or better class I guess would be ideal.
The Guide issue is simply because I want to be on a good lease or far enough back in to have a good chance and since i am 1500 miles away now I can't scout it and do it self-guided realistically. So if I am going to have to pay a service I might as well get a good one and let them do their job and focus on being a good and prepared client, while relaxing and taking it all in.
When placing a trail camera don't just look for a well used trail. What you want to do is look for a freshly used trail off by itself that goes from a north facing ridge, thick forest, brushy knob or some other similar bedding area to a food source. Don't forget water sources. Especially in the summer months the deer need water so look for a good trail going down too a creek surrounded by thick cover and place the camera 100 yards up from the water source.
Scent control is very important...
