lots of things you can do...i normally take mine compleatly out and put it in a diffrent spot if its not coming back to my eye right...i have also taken one single strand of the string and moved it from one side of the peep to the other...some times that helps some too....if you have a string loop you can also glue it to the center serving where it will let the peep open all the way on the draw...i dont like this way cause if you put too much glue on it the glue can go through the serving and into the string...then if you need to have the center serving replaced a lot of times the string will be trashed when you take the serving off...but just some things to think about to try...its kind of a trial and error type thing though
