RE: Achery Peep Sights.
I had the same problem a couple yrs ago but what i did was to draw the bow to full draw have my wife measure from the peep to the location where it gets tied off at. add about 1/2 inch for the knot and the small piece that slides on to the peep. the tubing only needs to streched enough to pull the peep around to line up, not to its breaking point. it has never broke during the season because i replace it before each season. no problem since.
