Does anyone use the Arizona EZ Fletcher? Is there a way to adjust how far down it fletches the vanes? I dont see a way to adjust it. I know you can turn the nock receiver to line up the cock vane but is there a way to shorten the length from nock to vane? The vanes are almost twice the distance from the nock then they were when bought. They are now an inch from the nock. Will this effect my arrow flight?
