I have used a feather Burner, however Pappy let me use a feather chopper and that's all I'll use now on the Turkey Feathers.
So my first choice is chopper, and second is a Feather Burner.
Just finished up on a dz arrows for a member of Twin Oaks. These are one's I chopped.
The one's below I made and I used a feather burner on.
