Thanks Jim, I'll try it. Using green fletchings I want the brightest colour there is like red or yellow and I'm not sure if I can achieve that so I just may end up dyeing it black, any recommendations?
Josh, I'm aware of the rib on the knock but I can load an arrow faster by having my knocking fletch a different colour than my other two feathers. My eyes can't focus fast enough sometimes and it takes too long to see that rib but that feather being a different colour just stands out to me, especially in low light conditions. I usually do mark my rib side of my knock with a marker also, it just seems so much easier than relying only on that rib in the knock.
