I make my own strings from 450or 452.I used to use the zebra's and really think that the advertized twist and zero peep rotation is a bunch of overblown hype,twist these color strands this way and that bundle that way[:-] .If a string stretches youre peep will rotate,there is no getting away from it.450&452 if they are made right and pre stretched or shot in have very little stretch at all hence no peep rotation
