If they come with winners choice , or vaportrail strings , why change? Otherwise factor in at least the cost of those and cabels allso . I cant believe the strings mathews customers let them give them , they are total junk , they make some nice bows , but if you are paying that much for a bow why dont they put a good string on it . Not mathews bashing , but give us a decent string and maybe more pepole will consider buying one .
