Not really sure. I think all different set ups shoot or react different with different vanes. There are so many variables draw length, arrow weight, length, bow speed, etc. a year ago I tested blazers, 2" fusions, 3" fusions, fobs, aae max hunters and flex fletch flash vanes. I found no difference in flight or accuracy with the blazers 2/3" fusions or the max hunters. The fobs and flex fletch grouped very similar and both grouped better for me out of my set up than the other 4. My brother did the same testing out of his bow and found no difference in any of them.
