Decided to remove my old feathers . They were 4 years old and not pristine anymore. I had yellow reflective wraps. I had purple barred 5 inch shield feathers with white barred. I went back with white reflective wraps this time. I chose blue barred with autumn barred 4 inch feathers this time. I wanted to speed up arrow some but was concerned about stability. They seem to shooting just as straight and much faster.
