I have a zebra string on my bow or whatever you call it and my peesight is twisting and getting in the way is there a device that can help this
thanks-sam

Check out the T.R.U. Speed Nok. It takes the place of a traditional nock set and aligns the peep to the same position every time.

T.R.U. Nock for me as well. I have used one for two years now and it is one of the best things I have bought in a while. I use the metal version instead of the speed version.... Keeps that peep nice and straight on my Mathews....

If you dont want to go with the speed nock, you could also get a tube style peep. thats what I did on my Q2 untill I got the string shot in, which took about 600 shots.
