I use white, four inch duravanes for the hens and cock. With florescent orange knocks. It's pretty easy to tell where you hit the animal by the color of blood on the arrow when you find it. If you hunt in woods like I do, you rarely see where the animal falls. The color of the blood on the vanes and or bubbles lets me know how far to expect to walk. The first set of arrows I bought had florescent green vanes, the only color available for the weight and brand arrow I shoot...it was like trying to find Michael Bloomberg at an NRA convention.
Did ya ever notice, the best tasting meats always come in their natural wrappings?
