I personally would not use the brass nocks , I would tie on soft knots , or at least 1 under soft knot
Easy to move if u need a little fine tuning with your loop , and if you would ever have to replace the d loop while hunting , the soft knots would allow you to position the d loop exactly where it was , versus trying to without knock points
Altho the brass ones would accomplish the same thing , I just do not like the metal ones on my string
I tie in one below and above...also depends on your ATA length and string angle...with a shorter bow I use both to keep the Dloop from potentially sliding and causing nock pinch but on a longer ata one on the bottom has worked for me in the past.
