Bigpapa, said it. However, this close to season I would just put one on with a tube aligner (I hate those things). After season get a Fletcher True Peep and put it in. Play with it, TRAIN your string and it should came back all lined up. While your at it get yourself a prestretched string from some place like Prostrings. After they break in after about a hundred shots you don't have to worry about your peep rotating on the draw.
