I bought a bow from my friend. I had to adjust the draw weight down and shorten the draw length. The bow I have is a PSE Drive and it has tuning marks to help with finding the nocking point. I noticed that my arrow was slanted slightly down due to the adjustments. I checked with the owners manual and it said that when using a release aid your arrow should be parallel with both marks. So, I was lucky enough to be able to loosen the D Loop, slide it down and get the arrow aligned with both marks. My arrow nock fits in the D Loop seeming fine but both the top and bottom knots touch my arrow nock. Should the knots touch the nock or should I have a small amount of space? I can nock and un-nock my arrow with what seems like the normal resistance. But y'all would know more about this than me.. Thanks.
For mine, I got my arrow in the correct position then I put serving below it and above it then the d loop outside of the serving so that I won't lose my center shot if the loop would happen to move and I won't have to worry about pinching.
