They fly really well for me. With Terminal T-Lock or Montec CS broadheads I can only shoot 1 arrow while tuning and sighting because they group too tight under 35 yards. Three arrows in a group the size of a silver dollar and damaged broadheads and arrow shafts at 35 yards, I shoot at different spots on the target with each arrow now. Their only weakness I have found is they tend to break in half when dying elk roll on them or brush against trees with them. ;-) but then I haven't found a shaft yet without this weakness.
