i was having peep twist issues (G5 meta in a pro-line string) and no luck twisting the string. I got a hold of the G5 Speed Studs and placed one in the string. moving it up or down rotates the peep without twisting strings/cables! one stud for single cam, both for dual cam. i actually just ran out and bought another set for my target bow today at lunch! works for me, and no tube stretched and aimed at your eye!
