RE: Is it just the fletching??
Most times the off color fletch will deceive the shooter. All the eye sees is the off color fletch flipping around.....it takes someone standing behind you to actually see the flight of the arrow. Your eyes should be on the target. If your friend sees them flying good, chances are they are....you should allow him to shoot your bow if capable and stand back and see for yourself. Of course if they are looping, a fixed bladed broadhead will let you know as well as paper tuning.
