OK so your string has settled in some during it's initial breakin period. The peep roated out of it;s original position. My question is this. Does the peep rotate at all? If not then this is a good thing. It shows the string is stabilized finally. Now do as recommended and take it to the shop and have them twist the string and or reposition the peep so it's facing straight back. Then do the same thing with your loop if you use one.

The worst thing you can do is use the loop to turn your peep. This not what a loop is for. It can be of some help if the peep is only off about 10-15 degrees, but what about if the peep were facing 180 degrees the other way? What are you going to do? Turn the loop 180 degrees? That would be stupid. The loop is supposed to face backwards so you can hook up to it. This might be an extreme example, but I'm just trying to be clear about what the primarypurpose of a loop is.

Using a loop gets explained a lot, too, like people assume because they use a loop that everybody does. Not always so.
