I think you did right by going with them. Those, Winner's Choice, Bucknasty, etc. are all leaders in string making. You mentioned peep twist, in fact that's how I missed a shot at a buck for the first time this past season. Drew back my bow and the peep was turned. Had been noticing it as a slight problem now and then late summer but figured it had never been a problem since I owned the bow so it would be good. Lesson learned, should have fixed the problem when I noticed it.
