I had same problem, 3 of 6 gt were not straight, sent them back, got much better with 125 gr field points, foc was low. still had problems as i would shoot a flier every 3 shots and not the same arrow. I took tip off arrow and put it under the string backwards so the vanes were at the front of the bow. their is a plastic shim sticking out and you could see where the vane was hitting it, i just trimmed it with a razor knife. Added weight to get foc to 13%, put in brass front inserts. can hit a quarter every shot at 20 yards. Now i shoot 100 gr slick trick magums, all I can say is "WOW"

Good luck. Stan
