I went with a red dot scope many years ago. It obviously has one dot and doesn't adjust. If I went back to pins it would be a single non-adjustable pin.
Just like a shot gun with the one bead, you adjust where on the target you aim based on distance. To sight it in, you stand 10' away from your target at shooting level and zero your arrow in. This I have found puts you dead on at 22 yards. From there it's a minor, aim a little high for 30 to 40 yards. Much cleaner IMO.
