Stixnstones, by reading your post I'm assuming you only tied the ends of the fletching down? For me I noticed more noise coming from my fletching when I started tying ends only...If you look closely at the photos you will see a small sinew thread in the center of my fletch that holds the fletch tightly to the shaft which reduced noise greatly! Once I started using this easy method I stopped hearing any noticeable noise...
