I got the 1/4" one after I got screwed out of a low light shot [:@]with the old peep. I like it but make sure You can keep your loop in the same place mine turns some times I think I'm gonna put a touch of super glue to hold it in place. The Bow shop said I'm gonna need a new string soon so that may be it. the best part is that even with it turned you can still see thru it. get it.
