Been tuning my own bows for a while and have gone through the process many many times and am happy with how my bows tune out (paper, bare shaft, broadhead). I've noticed that for whatever reasons certain times after tuning my bow seems to hold a lot steadier than other times. By unsteady I mean that pin drop where the bow seems to want to pull down, but sometimes the bow will come out and seem to not have that at all. I shoot the same bow, stabilizer, sight, draw weight/length (usually am just trying out different arrows so I re-tune). I've read that moving the D-loop up or down as well as lengthening and shortening it can affect how the bow holds? Is this what could be changing my bow hold? I've read that moving it up can help with that sight pin dropping under the target? How hight would you go? (arrow vs berger) Does nock set size/arrangement also affect any of that as well? I'd like to try and experiment with this but figured I'd try and get some advice on proper ways to do it first so I'm not totally shooting in the dark.
