To be honest, contrary to mathews advertising, the reverse twists do nothing for peep stabilization and consistancy. I have used Winners Choice, and after about 10 shots to get them settled in the peep never moves again. They do not use the reverse twists either. My personal strings take slightly longer to settle in, about 15 - 20 shots, and I do not have any peep problems, and they do not have reverse twists either. The key is serving tension, equal load on the string strands themselves when laying out the strings, and quality material.
