I am going to try a D Loop out this year after a few recommendations. I read the Thread on How to tie in nock sets and the D Loop. My question is this.....How do i tie the nock sets so that they can move to paper tune. If i tie the loop around them being loose i cant really get the loop as tight as it should be. Without the loop i just moved nocks. I am just alittle confused about this. It seems that once it is tied it is done. If someone could help me out with this. It is most likely something very simple. thanks.
