i have some arrows that are fletched with blue 5 inch shield cuts and a barred cock feather, the cresting is the simple black and white that comes on the kustom king premium cedars. thinking about it would be kinda cool to splice the 2 colors together, if even just the tail end of the feathers. im not really big on diferent colors unless it is to distinguish my diferent spine/ arrows set up for particular bows, even then its hard for me to coordinate fletching colors with bow colors so i just keep it simple.
