I had to add a twist or two to the string in my Trykon XL every 4 to 5 weeks because of creep. ( Stretch is like a rubber band, it returns to the original length, creep adds length and stays that way. ) Wasn't at all impressed with the fuse strings. Nice shooting bow, but you need to invest in some good aftermarket strings. That should stop all issues with your peep. Good luck.
