I went red dot scope which for all intensive purposes is single pin. I highly recommend it. It's much better because there is less clutter in the way. When you shoot a gun, you use one in and adjust your aim for yardage.
Sighting it in is very easy. Here is a slick trick. Stand 10' away from your target on a direct horizontal level. Sight in your shot to the bulleyes. That will work out to be dead on around 22 to 25 yards shot depending on your set up. Takes only a few mins at most.
