My hindsight is still on what is now my backup bow. When I got the new bow I just put on a pendulum. I tied a knot on the string and slid it up the string until it was right under the pin when I am at anchor. I put a kisser on the string and that is in the cornor of my mouth a anchor. That is all I used this year. Sight picture is very clear that way. I preceive the string as a blurr just to the right of the pin. I preceive the knot as a blot right under the pin. If the knot is not right under the pin I am not at the correct anchor. I took four deer this year with that system. Works for me...
