I am looking for a new string for my Bowtech Desert Stryker...I am unable to locate a factory string,,,so I am up to #1- my Pro building me one,,,which I believe that he is the best with a bow that I have ever seen,,,or #2-buying a Viper X or Vapor Trail....They both look good from the internet,,,but my question is,,,has anyone used them and if so what is your opinion??? Thanks
