click, a lot will have to do with the arrow trajectory of your setup. Personally, I use three pins. One at eight, one at 18, and one at 28. I use rather heavy arrows with my setup and get much more of a rainbow effect then a person using light carbons. But, I want to know exactly where my arrow is hitting at 28 yards, not guessing and compensating for it. If you choose to use a one pin setup, no matter what bow you shoot, you will have to do some compensating.
