Hyperflite 20" arrows work and fly true once you've dialed in your scope with practice target broadheads. I noticed that my field points did not match up with my broadheads when i dialed in my scope using field points. I tried two different manufacture braodheads with the same results. You have to sight in your crossbow with your practice broadheads if you want to be accurate with these hyperflite arrows. I harvested a nice buck amd doe both at 35 yards with a small window for an unobstructed shot in thick brush. The arrows flew exactly at aiming point.
