RE: Invisible Arrows?
Shooting at targets I don't think that it would make any difference what so ever. Shooting at animals though I like to have white fletchings, dip, and nock. It helps to see where the arrow goes and also helps in determining if you made a good hit or not, if you didn't see where the arrow hit, by the color of blood on the white vanes. It's alot easier to see blood on white than on brown or black.
