My preference is for one pin set at 20 yards. Out of my tree stands, this set up is good from underneath my stand and out to 32 yards with my particular set up. What I like about it is when I set my tree stands up, I mark the yardage around the stand and if a deer comes inside my " circle" and offers a clean shot, I do not have to guess my yardage and pick a corresponding pin. I used to use multiple pins but a friend talked me in to trying one pin 2 years ago. I have found it to be much simpler and quicker.
