I believe that the Carbon Express shafts provide the most accurate arrows available. EVEN THOUGH THEY ARE MADE IN KOREA. They now have an new shaft called the CXL (.003). I am going to shoot this arrow at 60 or 61 pounds with 2.35" AAE vanes, 70 grain nibb, Easton 2212 Unibushing(Found out from PDP at the trade show that these work together), and a Easton Super nock. Total weight=305-310 grains. These CXL shafts have a 23/64" Outside Diameter. They are sweet.
