You are very observant! The staggered fletch pattern was designed to provide a bit more accuracy at longer distances. I frequently practice shooting at 60 yards and can't tell any difference between my group size when shooting staggered fletch compared to regular fletch. My practice partners claim the staggered fletch is a bit louder while in flight. I have noticed the staggered fletch drifts more when shot in a crosswind than arrows with normal fletch — about 5″ more at 60 yards with my setup. I will return to using a normal fletch pattern next year.
