I often find that sometimes when I go to shoot my anchor doe'snt feel right and other times it feels good, I have a hard time being consistent with it, I shoot three fingers under and anchor behind my mouth up tight to my cheek bone tight to my face, I used to shoot two fingers under and one over split finger and I find that anchor feels good and easy to find but the arrows are all over the place and my groups the majority of the time are decent but just not consistent enough for me to attempt a deer kill. Is there anything I can attach to the string to help me find my anchor better.
