i could never use pins and switched to this site about 6 years ago. www.eradicator.com same idea but more like a gun site. i could never understand the use of multiple pins unless shooting out west or long distances but i guess it varies on the set up. i use to get a headache trying to think about which pin to use when i should have been concentrating on the approaching game. i would think most bows set up 60 to 70 pounds and with the right arrows could use a single pin from 10 yards to 22 yards and make it in the kill zone.i can say this site wont block your view of the game and made hunting with the bow more fun getting rid of that peep.
