First deer I killed was with a wood arrow that was bright yellow from nock to b.o.p.--shaft painted yellow, flo. orange cresting, with a chartruese feather tracer. I could see it in flight!
I use a "Safari Tuff" Arrowmaster with fletch cover now--whole arrow is hidden. I think the animals (other than turkey) are alerted by the arrows "flagging" back and forth more than the color, but this quiver takes care of both.
