I shoot and have shot GT, Easton, Beman, & Carbon Express shafts. I can't shoot GT 35/55 with broadheads, because they are too short for my draw length. To me which shaft is the toughest is a non issue. I've torn up very few carbon shafts and the few that I have probably would'nt have been saved had they been a different brand. One thing that usually comes into play when I am trying to find the "right" arrow for a particular bow is the arrow weight. Unless you want to use weight tubes this may be a factor in deciding on a brand.
