I have a D-loop. For the one pin sights do you just aim a little high and learn how much higher you need to aim to adjust for arrow fall for distance shots? As with the multiple pins you just sight the pins in for the yardage, sighting them in is when you find errors occur? I like the kisser as it helps me know were to draw the string to, its probably not needed for more experienced bow hunters but for learning, it feels helpful. Thanks.
