It depends completely on your set-up. For MOST bows a single pin set at 20-25yds is fine. If you want to shoot much past 30 yds, you're beter off to have a multi-pin sight or a single pin slider sight. I'm one of the few "odd" guys that set pins based on the ballistics of a particular bow. On my 2 main shooter bows that shoot arrows in the 280fps range, I set pins at 24, 32, 40, 48, 55yds, on my older 60# Hoyt Striker II which shoots mid 250's, I set my first pin at 22, second at 28, 34, 40, 45. Each of us will have our own preferences, for me, my bows are set-up for "hunting accuracy" as much as anything.
