how about this question that came up this year with my set up -

Do you need or should you use a nock with the loop? My buddy who sets up my bow just ties one on and that worked fine for me. However, when I had some work done on the bow at Gander My, they use a nock (I believe below upper part of loop). That seems to work fine also. It was funny, my buddy said "why is the nock on there", then he changed it, then went to GM and they were going to change it (center shot off slightly), so I asked why they do it, and the GM person showed me the loop package and they recommend doing it. So I have a loop with the nock now, I think. (I really did have my loop done 3 times this year - was having tuning issues).

What do people think/do?
