I use a shurtz peep, and my bow also has a twisted string. After many shots for stretching at home. I attached a tru-ball peep aligner, with string loop. My peep is lined up every shot since. One of my first bows had the stretch tubing style peep. I eliminated that for a few reasons. 1 it broke, and I got snapped in the face, it wore, and stretched so didn' t align same over time, and had to be replaced. The tubing makes noise upon release.
